Call (301) 395-3831

Exterior window sealing fails in Colesville homes as temperature cycling expands and contracts the frame and siding over years. When the sealant cracks or separates, water gets into the joint, behind the siding, and into the rough opening. Our team removes old failed sealant completely, prepares the joint, and applies the correct exterior-grade silicone or siliconized latex in a clean consistent bead that bonds to both surfaces.

Colesville sits between the Northwest Branch and Paint Branch stream valleys, its 1960s and 70s colonials, split-levels, and ranches grown up under a now-mature tree canopy. Fifty-year-old houses under big trees have a particular rhythm: gutters that work for a living and the steady aging-out of everything original.

Frequently Asked Questions

Paintable siliconized latex for wood and fiber cement frame-to-siding joints. Pure silicone for glass-to-frame joints and aluminum frame transitions. Our team selects the correct product for the specific substrate in your Colesville home.

It must be removed. Applying new sealant over failed old sealant does not bond properly to the substrate. The new material fails quickly because it is adhered to loose old caulk instead of the window frame material itself.

It addresses one common entry point. If water is entering through a failed seal around the window frame, resealing stops that entry. If there are other sources such as flashing failure above the window or a failed IGU, those are separate issues. Our team notes any other visible causes during the visit.

A properly prepared and applied exterior sealant lasts five to seven years in Maryland's climate. Product quality and surface prep are the two biggest factors. Thin consumer caulk on an unprepared joint lasts one to two seasons.

What We See in Colesville Homes

Colesville sits between the Northwest Branch and Paint Branch stream valleys, its 1960s and 70s colonials, split-levels, and ranches grown up under a now-mature tree canopy.

That ground-level entry changes ladder access and how exterior runs get routed, so the approach is planned before anyone is on a ladder.
