Why fall is the right time to seal up

Silver Spring summers are humid and the winters bring real cold snaps, and the swing between the two is hard on every seal in a house. Caulk dries out and pulls away from trim, weatherstripping flattens, and door sweeps wear thin. Most homeowners only notice in January, when a room feels drafty or the heat seems to run constantly. Fall is the better moment to deal with it. Temperatures are still mild enough for caulk and adhesives to cure properly, and you can find problems before you are paying to heat air that leaks straight back outside.

How to find the leaks

The easiest test is your own hand on a cool, windy day. Hold it near the edges of exterior doors, around window sashes, at baseboards on outside walls, and around outlets on exterior walls, and feel for moving air. Daylight showing around a closed door is a sure sign the weatherstripping has failed. Another simple check is to close a door or window on a sheet of paper. If it slides out with no resistance, the seal is not making contact. Make a list as you go, because sealing work is easiest when every gap is handled in one visit.

Weatherstripping exterior doors

Exterior doors are usually the biggest source of drafts. The weatherstripping set into the door frame compresses over time and stops sealing against the door, and the sweep or threshold seal along the bottom wears out from daily foot traffic. Replacing these parts is a modest job, but fit matters. Weatherstripping that is too thick can keep the door from latching, and a sweep set too low will drag on the floor. If the door itself has sagged or moved out of square, new weatherstripping will not fix the gap, and the door needs to be adjusted at the hinges or strike plate first. That is the same door work that fixes sticking doors.

Sealing windows

Windows leak in two places: where the sash meets the frame, and where the frame meets the wall. Sash leaks are usually handled with new weatherstripping suited to the window type, since double-hung, sliding, and casement windows each seal differently. Leaks around the frame are a caulking job. On the inside, gaps between the window trim and the wall can be sealed with a paintable caulk. On the outside, the joint between the window frame and the siding or brick needs an exterior-grade sealant that holds up to sun, rain, and temperature changes. Old caulk should be removed first. New caulk laid over cracked, failing caulk does not bond and will open up again.

Caulking done properly

Good caulking is mostly preparation. The joint needs to be clean and dry, with old material cut and scraped out and loose paint removed. The right product depends on the location. Interior trim joints call for a paintable acrylic caulk, while tubs, showers, and sinks need a caulk made for wet areas, and exterior joints need a sealant rated for outdoor use. The bead should be sized to the gap and tooled smooth so it presses into both surfaces. Gaps that are too wide or deep for caulk alone need a backer rod pushed in first, so the caulk can stretch and move with the house instead of cracking.

Other spots worth checking

Doors and windows get most of the attention, but several other places let cold air in. Attic hatches and pull-down stairs often have no seal at all. Gaps where pipes, cables, and vents pass through exterior walls can be sealed with caulk or foam. Garage doors that lead into the house should seal as tightly as any exterior door. Outlet and switch covers on exterior walls can be fitted with foam gaskets. Outside, check that gutters are fastened securely and that caulk is intact where siding meets trim, so fall rain does not get behind it.

What a handyman visit covers

AR and Sons Handyman handles weatherstripping and caulking as part of its home maintenance service, along with the door adjustments that so often go with it. Because this work is a list of small items spread around the house, it suits a single visit well. Walk through the house before the appointment, note every draft and cracked bead of caulk you found, and the work can be handled room by room. If something on the list turns out to be a bigger problem, like rotted trim under failing caulk, you will know about it before winter instead of after. Sealing work also pairs naturally with other small repairs, such as tightening loose door hardware, replacing a worn threshold, or fixing a gate latch, so those can go on the same list.

Plan ahead of the first cold snap

Sealing a house is not complicated, but it is easy to put off until the first cold morning. Scheduling the work in early or mid fall gives caulk and sealants time to cure in good conditions and leaves time to deal with any repairs that turn up.
