Exterior window caulk in Maryland fails every few years from the constant expansion and contraction of freeze-thaw cycles. When the caulk pulls away from the window frame or cracks through, rain water enters the wall cavity where it stays and causes rot. Jacob re-caulks exterior windows throughout Gaithersburg homes, removing the old failed caulk first rather than caulking over it.
Jacob is based right here in Gaithersburg. You are not getting someone who drives in from another county. He knows the neighborhoods, the typical home styles, and the kinds of problems that come up in homes built in the 80s, 90s, and 2000s throughout this area.
Jacob holds MHIC #112963, Maryland's home improvement contractor license. Licensed and insured.

Frequently Asked Questions
Cost depends on the number of windows and their accessibility. Sealing all windows in one visit is more efficient than doing them one at a time. Property Renovators Handyman Services is based in Gaithersburg, so scheduling is straightforward and he knows the area. Jacob gives you a quote after counting the windows and checking their condition.
Quality elastomeric or silicone caulk on a well-prepared surface lasts 5 to 10 years in Maryland's climate. Low-grade latex caulk or caulk applied over old failed caulk fails faster. If caulk is cracking or pulling away from the frame, it has failed regardless of its age.
No. New caulk applied over old failed caulk does not bond properly and fails quickly. The old caulk must be removed down to a clean surface before new caulk is applied. Jacob removes the old material completely before resealing.
Silicone or silicone-modified elastomeric caulk holds up better than latex in Maryland's temperature range. Silicone stays flexible through freeze-thaw cycles rather than cracking and does not allow mold growth the way some latex formulas do.
Leaks that only appear during driving rain or wind-driven rain typically point to gaps at the upper corners of the window frame or to failed sealant on the sides of the frame rather than the top. Jacob inspects all four sides of each window rather than just the obvious areas.
Jacob uses ladders for upper-floor window sealing. Most Gaithersburg homes with standard two-story construction are within ladder reach. Three-story homes or unusually high window placements may require discussion before scheduling.
Interior window sealing stops air infiltration and improves energy efficiency. If you are noticing drafts around windows from inside, the interior gap between the window frame and the drywall is a common source. Jacob can address both interior and exterior sealing in the same visit.
The caulk gun work itself is within reach of most homeowners. The part that gets skipped is the complete removal of old caulk and the surface prep. Applying new caulk over old failed material gives you a joint that looks better for a few months and then fails again.
A single-story home with ten windows typically takes two to three hours for full exterior sealing. Two-story homes take longer. Jacob works systematically through all windows in one visit.
