Reducing Condensation Controlling Ground Water Exterior Remedies Interior Remedies Water that comes through cracks Basement StairsSqueaks in stairs are usually caused by a loose tread rubbing against a riser or the stringers when someone steps on the stair. Treads become loose when joints open due to shrinkage, or when supporting blocks or nails work loose. Once you pinpoint the location of the noise, you can usually remedy it. You probably already know which steps are the noisemakers in your staircase. - If the noise comes from where you step,
concentrate your repair efforts there.
- If the noise comes from one side when you
step in the center, or if it comes from the rear of the tread when
you step at the front, first secure the place where you step, then
move to the apparent source of the noise.
- If the stairs are accessible from
underneath, work on them from below so your repairs won't show.
You can use wedges, brackets, or wood blocks to secure the treads
to the risers.
- If you don't have access from below,
you'll have to work from above.
- First, try lubricating the stairs with
powdered graphite or talcum powder.
- Forcefully blow the powdered graphite or
talcum powder into the joints, especially where the backs of the
treads met the risers.
- To prevent the wood from splitting, drill
pilot holes before inserting nails or screws.
- Counterbore the holes if you plan to fill
them with dowel plugs rather than wood putty.
- If you drive in wedges, you'll have to
remove any shoe molding first.
- After driving in the wedges with a hammer, cut them flush with the riser, using a utility knife, and replace the shoe molding to conceal them.
BanistersMost wood banisters consist of one or two handrails, balusters, and one or two more supporting newel posts. Repeating use can weaken the banister, resulting in loose handrails, balusters or posts. Methods for tightening loose parts involve inserting wedges or securing loose joints with screws. - If you're using screws, drill pilot holes
for them to prevent the wood from splitting.
- Use an electric drill with a combination
bit so you can sink the screw heads.
- To conceal them, fill the screw holes with wood putty - preferably colored to match the wood - and sand the putty smooth.
Controlling Moisture in the BasementThe most common basement problem a homeowner faces is water. The problem can range in seriousness from damp walls and floors to water gushing out of a crack. The source may be simply humid air condensing on cool surfaces or ground water finding its way through your basement's walls or floor. Before you can correct the problem, you'll need to determine the source of the water. Where is the Water Coming From?If you can see water flowing out of a crack in a wall or floor, you know that the source is ground water. In the absence of such obvious evidence, you'll have to make a test to determine whether condensation or ground water causes the dampness in your basement. - Cut two twelve-inch squares of plastic
sheeting or aluminum foil.
- Tape one to the inside of an outside wall
and one to the basement floor (make sure the surfaces are
thoroughly dry).
- After two or three days, remove the
plastic or foil and examine the surface that was next to the wall
or floor.
- If it's dry, the culprit is condensation.
- If it's wet, it's a sign that ground water is seeping through the wall or floor.
Reducing CondensationWhen the basement air is humid, the moisture in the air may condense on cool surfaces, such as cold water pipes, concrete or masonry walls, or a concrete floor. Though you can apply a coating to reduce condensation, it's best to lower the air's humidity, using these suggestions: - Improve ventilation by opening basement
windows or installing an exhaust fan in the basement.
- Raise the temperature in the basement.
- Vent moist air from a clothes dryer to
the outside.
- Install a dehumidifier in the basement
area.
- Insulate cold water pies and basement walls.
Controlling Ground WaterWhen water collects next to a foundation wall, or when the water table (the water level under your property) is higher than your basement floor, hydrostatic pressure can force water through cracks, joints and porous areas in concrete walls and floors and through cracked or crumbling mortar joints in masonry walls. Causes can include: - Poor construction practices.
- Clogged or non-existent footing drains.
- Poorly applied or nonexistent
waterproofing on the foundation
- Cracks through the wall.
- Improper grading.
Correcting any of these problems is a major job that requires digging out the foundation to the bottom of the footings. Though this may very well be the most permanent repair, first try the remedies that follow. If they don't work, then you'll have to contact a foundation engineer or contractor for a more lasting solution. CAUTION: If you see horizontal cracks in a wall that's bowing inward, long, vertical cracks wider than 1/4 inch, or a crack that's getting wider (measure periodically), you have a structural problem. Contact a soils or foundation engineer at once. Exterior RemediesRoof and surface water collecting next to the foundation may be causing the dampness in your basement. Make a careful inspection outside, using the following checklist, and correct any problems you find. - Gutters and downspouts should be clear
and should direct water away from the foundation.
- For tips on cleaning gutters and
improving drainage at downspouts, click here.
- Make sure you have proper grading around
the house. The ground should drop one inch per foot for the first
ten feet away from the foundation walls to ensure good surface
drainage.
- Planting beds next to the foundation
should keep water from collecting or pooling.
- Window wells around basement windows should be free of debris, have good drainage, and be properly sealed at the wall.
Interior RemediesThese simple interior repairs may alleviate or cure your water problems: - Apply a coating to the wall. Most
coatings are painted on, though some are plastered on with a
trowel. Except for epoxy coatings, all are cement-base products
with various additives. Epoxy does the best job. Look for coatings
at home improvement or masonry supply centers.
- Patch cracks in walls and floors with
Portland or hydraulic cement patching compound. Hydraulic cement
expands and dries quickly, even in wet conditions. Cracks wider
than 1/8 inch should be undercut-chiseled out so the bottom of the
crack is wider than the. This will prevent water pressure from
popping out of the patch.
- Chisel out a groove along the wall if
water is entering through a floor/wall joint. Fill the groove with
hydraulic or epoxy cement and cove (form in a concave shape).
- Chisel out cracked mortar joints in masonry walls and fill them with hydraulic or epoxy cement.
Water that comes through cracks in a concrete floor or through the joint between the floor and wall is caused by hydrostatic pressure.In addition to those described above, remedies include: - Installing drains under the floor.
- Adding a sump pump.
- Laying a new floor over a waterproof membrane placed on the old floor.
