I used to hang an extra woolly robe in my bathroom because my post-shower route took me past a window so drafty it made me wonder about the etymology of “window.” Turns out it comes from the Anglo-Saxon “vindr” and “auga,” which translates as “wind eye.” How appropriate.

If the “wind eye” focused on you last winter, but you’re not ready to invest in new windows, you can still cut your energy bills if you seal those air leaks—and if you do so now, you’ll prevent cool air from escaping your home this summer.

Here are three low-cost tips to help keep air leaks at bay:

#1: For most windows: Just fill the gaps.

Easier said than done if you’re dealing with old, flaky caulk, weather stripping, or adhesive that’s really tough to remove. But if you don’t clean it off well, your new caulk and stripping won’t adhere well and could peel away before you see any benefits.

However, a common household product, petroleum jelly, removes that adhesive goo quite well. Just rub the jelly over the sticky goo, let it sit for a few minutes, then wipe away. Another swipe with rubbing alcohol will remove the greasy film left from the jelly. (This technique, by the way, also works for removing price labels.)

#2. For older windows with rattling panes: Make baffles.

Cut quarter-round pine strips to fit. Use finishing nails and wood glue to secure them just inside the framed glass. Once you’ve caulked and painted the strips to match, they will disappear into the framework and look like part of the original window. It worked wonderfully on my 1920-era casement windows.

#3. If you want window treatments, too: Install waffle shades.

Folding fabric shades that are made with cells that trap air have great insulating properties—so good that some of them qualify for federal energy rebates, which have been extended into 2011. They start at around $50—still less expensive than new windows—and you get a new look, too.

Leaky windows are a big deal, winter or summer. What ways have you found to fix your windy windows?

Here’s how to get the bathroom of your dreams without making your budget a nightmare.

You dream about a bathroom that’s high on comfort and personal style, but you also want materials, fixtures, and amenities with lasting value. Wake up! You can have both.

A mid-range bathroom remodel is a solid investment, according to Remodeling Magazine’s annual Cost vs. Value Report. An average bath remodel of $16,128 will recoup about 72.5% of those costs when it’s time to sell your home, and a more extensive $51,374 job returns about 63.6%. In addition, you can maximize the value of your investment by using these smart strategies, which will create a stylish yet budget-friendly bathroom.

1. Stick to a Plan

A bathroom remodel is no place for improvisation. Before ripping out the first tile, think hard about how you will use the space, what materials and fixtures you want, and how much you’re willing to spend.

The National Kitchen and Bath Association (NKBA) recommends spending up to six months evaluating and planning before beginning work. That way, you have a roadmap that will guide decisions, even the ones made under remodeling stress. Once work has begun — a process that averages two to three months — resist changing your mind. Work stoppages and alterations add costs. Some contractors include clauses in their contracts that specify premium prices for changing original plans.

If planning isn’t your strong suit, hire a designer. In addition to adding style and efficiency, a professional designer makes sure contractors and installers are scheduled in an orderly fashion. A pro charges $100 to $200 per hour, and spends 10 to 30 hours on a bathroom project.

2. Keep the Same Footprint

You can afford that Italian tile you love if you can live with the total square footage you already have.

Keeping the same footprint, and locating new plumbing fixtures near existing plumbing pipes, saves demolition and reconstruction dollars. You’ll also cut down on the dust and debris that make remodeling so hard to live with.

Make the most of the space you have. Glass doors on showers and tubs open up the area. A pedestal sink takes up less room than a vanity. If you miss the storage, replace a mirror with a deep medicine cabinet.

3. Make Lighting a Priority

Multiple shower heads and radiant heat floors are fabulous adds to a bathroom remodel. But few items make a bathroom more satisfying than lighting designed for everyday grooming. You can install lighting for a fraction of the cost of pricier amenities.

Well-designed bathroom task lighting surrounds vanity mirrors and eliminates shadows on faces: You look better already. The scheme includes two ceiling- or soffit-mounted fixtures, and side fixtures or sconces distributed vertically across 24 inches (to account for people of various heights). Four-bulb lighting fixtures work well for side lighting.

Today, shopping for bulbs means paying attention to lumens, the amount of light you get from a bulb — i.e., brightness. For these bathroom task areas, the Lighting Research Center recommends:

• Toilet: 45 lumens
• Sink: 450 lumens
• Vanity: 1,680 lumens

4. Clear the Air

Bathroom ventilation systems may be out of sight, but they shouldn’t be out of mind during a bathroom remodel.

Bathroom ventilation is essential for removing excess humidity that fogs mirrors, makes bathroom floors slippery, and contributes to the growth of mildew and mold. Controlling mold and humidity is especially important for maintaining healthy indoor air quality and protecting the value of your home — mold remediation is expensive, and excess humidity can damage cabinets and painted finishes.

A bathroom vent and water closet fan should exhaust air to the outside — not simply to the space between ceiling joists. Better models have whisper-quiet exhaust fans and humidity-controlled switches that activate when a sensor detects excess moisture in the air.

5. Think Storage

Bathroom storage is a challenge: By the time you’ve installed the toilet, shower, and sink, there’s often little space left to store towels, toilet paper, and hair and body products. Here are some ways to find storage in hidden places.

• Think vertically: Upper wall space in a bathroom is often underused. Freestanding, multi-tiered shelf units designed to fit over toilet tanks turn unused wall area into found storage. Spaces between wall studs create attractive and useful niches for holding soaps and toiletries. Install shelves over towel bars to use blank wall space.

• Think moveable: Inexpensive woven baskets set on the floor are stylish towel holders. A floor-stand coat rack holds wet towels, bath robes, and clothes.

• Think utility: Adding a slide-out tray to vanity cabinet compartments provides full access to stored items and prevents lesser-used items from being lost or forgotten.

6. Contribute Sweat Equity

Shave labor costs by doing some work yourself. Tell your contractor which projects you’ll handle, so there are no misunderstandings later.

Some easy DIY projects:

• Install window and baseboard trim; save $250.

• Paint walls and trim, 200 sq.ft.; save $200.

• Install toilet; save $150.

• Install towel bars and shelves; save $20 each.

7. Choose Low-Cost Design for High Visual Impact

A “soft scheme” adds visual zest to your bathroom, but doesn’t create a one-of-a-kind look that might scare away future buyers.

Soft schemes employ neutral colors for permanent fixtures and surfaces, then add pizzazz with items that are easily changed, such as shower curtains, window treatments, towels, throw rugs, and wall colors. These relatively low-cost decorative touches provide tons of personality but are easy to redo whenever you want.

You’ll be ready for winter’s worst and head off expensive repairs when you complete this checklist of 10 essential fall maintenance tasks.

1. Stow the mower.

If you’re not familiar with fuel stabilizer, you should be. If your mower sits for months with gas in its tank, the gas will slowly deteriorate, which can damage internal engine parts. Fuel stabilizer ($10 for a 10-ounce bottle) prevents gas from degrading.

Add stabilizer to your gasoline can to keep spare gas in good condition over the winter, and top off your mower tank with stabilized gas before you put it away for the winter. Run the mower for five minutes to make sure the stabilizer reaches the carburetor.

Another lawn mower care method is to run your mower dry before stowing it.

1. When the mower is cool, remove the spark plug and pour a capful of engine oil into the spark plug hole.

2. Pull the starter cord a couple of times to distribute the oil, which keeps pistons lubricated and ensures an easy start come spring.

3. Turn the mower on its side and clean out accumulated grass and gunk from the mower deck.

2. Don’t be a drip.

Remove garden hoses from outdoor faucets. Leaving hoses attached can cause water to back up in the faucets and in the plumbing pipes just inside your exterior walls. If freezing temps hit, that water could freeze, expand, and crack the faucet or pipes. Make this an early fall priority so a sudden cold snap doesn’t sneak up and cause damage.

Turn off any shutoff valves on water supply lines that lead to exterior faucets. That way, you’ll guard against minor leaks that may let water enter the faucet.

While you’re at it, drain garden hoses and store them in a shed or garage.

3. Put your sprinkler system to sleep.

Time to drain your irrigation system. Even buried irrigation lines can freeze, leading to busted pipes and broken sprinkler heads.

1. Turn off the water to the system at the main valve.

2. Shut off the automatic controller.

3. Open drain valves to remove water from the system.

4. Remove any above-ground sprinkler heads and shake the water out of them, then replace.

If you don’t have drain valves, then hire an irrigation pro to blow out the systems pipes with compressed air. A pro is worth the $75 to $150 charge to make sure the job is done right, and to ensure you don’t have busted pipes and sprinkler head repairs to make in the spring.

4. Seal the deal.

Grab a couple of tubes of color-matched exterior caulk ($5 for a 12-ounce tube) and make a journey around your home’s exterior, sealing up cracks between trim and siding, around window and door frames, and where pipes and wires enter your house. Preventing moisture from getting inside your walls is one of the least expensive — and most important — of your fall maintenance jobs. You’ll also seal air leaks that waste energy.

Pick a nice day when temps are above 50 degrees so caulk flows easily.

5. De-gunk your gutters.

Clogged rain gutters can cause ice dams, which can lead to expensive repairs. After the leaves have fallen, clean your gutters to remove leaves, twigs, and gunk. Make sure gutters aren’t sagging and trapping water; tighten gutter hangers and downspout brackets. Replace any worn or damaged gutters and downspouts.

If you find colored grit from asphalt roof shingles in your gutters, beware. That sand-like grit helps protect shingles from the damaging ultraviolet rays of the sun. Look closely for other signs of roof damage (#5, below); it may be time for a roofing replacement.

Your downspouts should extend at least 5 feet away from your house to prevent foundation problems. If they don’t, add downspout extensions; $10 to $20 each.

6. Eyeball your roof.

If you have a steep roof or a multistory house, stay safe and use binoculars to inspect your roof from the ground.

Look for warning signs: Shingles that are buckled, cracked, or missing; rust spots on flashing. Any loose, damaged, or missing shingles should be replaced immediately.

Black algae stains are just cosmetic, but masses of moss and lichen could signal roofing that’s decayed underneath. Call in a pro roofer for a $50 to $100 eval.

A plumbing vent stack usually is flashed with a rubber collar — called a boot — that may crack or loosen over time. They’ll wear out before your roof does, so make sure they’re in good shape. A pro roofer will charge $75 to $150 to replace a boot, depending on how steep your roof is.

7. Direct your drainage.

Take a close look at the soil around your foundation and make sure it slopes away from your house at least 6 vertical inches over 10 feet. That way, you’ll keep water from soaking the soils around your foundation, which could lead to cracks and leaks.

Be sure soil doesn’t touch your siding.

8. Get your furnace in tune.

Schedule an appointment with a heating and cooling pro to get your heating system checked and tuned up for the coming heating season. You’ll pay $50 to $100 for a checkup.

An annual maintenance contract ensures you’re at the top of the list for checks and shaves 20% off the cost of a single visit.

Change your furnace filters, too. This is a job you should do every two months anyway, but if you haven’t, now’s the time. If your HVAC includes a built-in humidifier, make sure the contractor replaces that filter.

9. Prune plants.

Late fall is the best time to prune plants and trees — when the summer growth cycle is over. Your goal is to keep limbs and branches at least 3 feet from your house so moisture won’t drip onto roofing and siding, and to prevent damage to your house exterior during high winds.

For advice on pruning specific plants in your region, check with your state extension service.

10. Give your fireplace a once-over.

To make sure your fireplace is safe, grab a flashlight and look up inside your fireplace flue to make sure the damper opens and closes properly. Open the damper and look up into the flue to make sure it’s free of birds’ nests, branches and leaves, or other obstructions. You should see daylight at the top of the chimney.

Check the firebox for cracked or missing bricks and mortar. If you spot any damage, order a professional fireplace and chimney inspection. An inspection costs $79 to $500.

You fireplace flue should be cleaned of creosote buildup every other year. A professional chimney sweep will charge $150 to $250 for the service.

Labor Day through Halloween is your window for preparing lawns for a lush spring.

Although spring lawn care gets all the attention, fall lawn care is the make-it or break-it season for grass.

“I’m already thinking about next year,” says John Dillon, who takes care of New York City’s Central Park, which features 200 acres of lawn in the middle of Manhattan. “The grass I grow this fall is what will be there next spring.”

Fall lawn care is no walk in the park. It’s hard work, and Dillon guides you through the four basic steps.

1. Aeration

Aeration gives your lawn a breather in autumn and provides room for new grass to spread without competition from spring weeds. Aeration tools pull up plugs of grass and soil, breaking up compacted turf. That allows water, oxygen, and nutrients to reach roots, and gives seeds room to sprout.

If kids frequently play on your lawn, plan to aerate twice a year — fall and spring. If your lawn is just for show, then aerate once a year — and maybe even once every other year.

A hand-aerating tool ($20), which looks like a pitchfork with hollow tines, is labor-intensive and meant for unplugging small sections of grass. Gas-powered aerating machines (rental, $20/hour) are about the size of a big lawn mower, and are good for working entire lawns. Bring some muscle when you pick up your rental: Aerating machines are heavy and can be hard to lift into your truck or SUV.

Depending on the size of your property, professional aeration costs about $150.

2. Seeding

Fall, when the soil temperature is about 55 degrees, is the best time to seed your lawn because turf roots grow vigorously in fall and winter. If you want a lush lawn, don’t cheap out on the seed.

Bags of inexpensive seed ($35 for 15 pounds) often contain hollow husks, weed seed, and annual rye grass seed, which grows until the first frost then drops dead. Splurge on the good stuff ($55 for 15 pounds of Kentucky Bluegrass seed), which resists drought, disease, and insects.

Water your new seed every day for 10 to 20 days until it germinates.

3. Fertilizing

A late fall fertilization — before the first frost — helps your grass survive a harsh winter and encourages it to grow green and lush in spring. Make your last fertilization of the year count by choosing a product high (10% to 15%) in phosphorous, which is critical for root growth, Dillon says.

Note: Some states are banning phosphorous-rich fertilizers, which are harmful to the watershed. In those places, look for nitrogen-rich fertilizers, which promote shoot and root growth. Check with your local extension service to see what regulations apply in your area.

4. Mulching

Instead of raking leaves, run over them a couple of times with your mower to grind them into mulch. The shredded leaves protect grass from winter wind and desiccation. An added bonus — shredded leaves decompose into yummy organic matter to feed grass roots.

A mulching blade ($10) that attaches to your mower will grind the leaves even finer.
