Sealing & Caulking Solutions for Washington D.C. Metro Area

Sealing and Caulking

Energy prices have been rising in the US over the past few years leading to higher heating and cooling costs. It is therefore important to check your home to insure that your heating dollars aren't being wasted. By preventing leaks, you keep in valuable heat and make your home more comfortable while keeping those escalating energy bills low.

Locating Air Leaks

Most air leaks in homes can easily be noticed in winter. Such air leaks are often referred to as drafts. Most significant air leaks are hidden in the attic and basement. These are the leaks that are likely raise your energy bill and make your house uncomfortable. Locating such leaks can be difficult because they are often hidden under your insulation.

In winter, warm air rises in your house. This air, which you have paid to heat, is just wasted as it ends up in the attic. You will find attics in most homes comfortable in winter.

Air leaks in a typical home can be found behind knee-walls; attic hatch; wiring holes; plumbing vent; recessed light; furnace flue or duct chase-way; basement rim joists where the foundation meets the wood framing; and other others.

Sealing Air Leaks

It is not practical to expect to find and seal all the holes in your attic. Instead the biggest savings come from plugging the large holes. We locate the areas where leakage is likely to be greatest: where walls meet the attic floor, dropped soffits, dropped-ceiling areas and behind or under attic knee-walls.

We look for dirty insulation — this indicates that air is moving through it. Your dropped soffits may be covered with insulation and hard to see. We push back the insulation and scoop it out of the soffits. We put this insulation back over the soffit once the stud cavities have been caulked.

Outside air drawn in through basement leaks is exacerbated by the chimney effect created by leaks in the attic. As hot air generated by the furnace rises up through the house and into the attic through leaks, cold outside air gets drawn in through basement leaks to replace the displaced air. This makes a home feel drafty and contributes to higher energy bills. After sealing attic air leaks, we complete the job by sealing basement leaks, to stop the chimney effect.

Duct Sealing

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, about 20 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable no matter how high the thermostat is set.

You can tell your duct system is performing poorly when you have high summer and winter utility bills; you have rooms that are difficult to heat and cool; you have stuffy rooms that never seem to feel comfortable; your ducts are located in an attic, crawlspace, or the garage or you have lose or tangled ducts in your system.

A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer.
