This reconstruction in Allen, TX involved a homeowner who had no idea a slow A/C drain overflow was rotting the siding behind a box window. The property sits in the Shadow Lakes North neighborhood of Allen, Texas. For months, condensate from the air conditioning system’s secondary drain line had been emptying onto the exterior wall instead of draining away properly. By the time the crew arrived, the moisture had already reached the masonite-type siding and the wood framing underneath. The homeowner, a longtime customer, had already replaced the A/C system and had the drain lines cleared, which stopped the ongoing runoff. That gave the crew a stable, dry area to begin repairs the next day.
What we found in Allen
The inspection showed water damage concentrated around the box window where the A/C drain line had been discharging. The masonite-type siding had absorbed moisture over an extended period, causing it to swell and deteriorate. Trim boards around the window showed similar decay. Once we opened up the area, we found the framing behind the siding had also taken on damage from the sustained exposure. Because the homeowner had already addressed the source, our job focused entirely on removing and rebuilding the damaged exterior components.
Rainy Day’s role
Rainy Day Restoration & Roofing has served North Texas families since 1999, and we’re one company from first call through rebuild. Josh Hopewell led this reconstruction project, documenting the damage and coordinating the repair. This particular job involved siding, trim, and framing work rather than mold or water mitigation, so no specialty licensing or certification applies to the scope performed here.
The reconstruction in Allen, TX, step by step
First, we inspected the affected wall section to determine how far the damage extended. Next, we removed the damaged trim and siding pieces around the box window. After exposing the framing, we assessed which structural members needed replacement and repaired them accordingly. Once the framing was solid, we installed new siding and trim to match the surrounding materials. Finally, we caulked all seams and painted the new materials so the repair blended with the rest of the exterior. The entire job, from inspection to finished paint, wrapped up in a single day.
What the photos show
The photos document the sequence from initial condition through completed repair. Early images show the deteriorated siding and trim around the window before removal. Later photos capture the exposed framing once the old materials came off, followed by the new siding and trim installed in their place. The final images show the finished, painted exterior matching the surrounding wall.












Why moisture damage is worth taking seriously
A slow, hidden leak can cause more damage than a sudden one because it goes unnoticed for so long. In this case, the A/C secondary drain line had been discharging onto the same spot repeatedly, so the moisture never had a chance to dry out between cycles. That kind of sustained exposure breaks down masonite-type siding faster than typical weather exposure. It can also reach wood framing, which compromises the structure behind the exterior finish. Homeowners should periodically check that both primary and secondary A/C drain lines route water away from the house, not against it.
Result and next step
This reconstruction in Allen, TX finished with new siding, trim, and framing installed, caulked, and painted to match the home’s exterior. The A/C system replacement and drain line clearing had already stopped the source of moisture, so the repair addressed the resulting damage rather than an ongoing leak. The approximate cost for this scope fell under $2,500. Property owners noticing swollen siding or peeling paint near an A/C line should have the area inspected before the damage spreads further.
Guidance for property owners in Allen and North Texas
If you notice discoloration or soft spots on siding near an air conditioning unit or drain line, don’t wait to have it checked. Small leaks compound over time, and by the time damage becomes visible, framing underneath may already need attention.

Frequently asked questions
What causes an A/C secondary drain line to overflow?
A secondary drain line usually overflows when the primary line clogs or when the system isn’t draining properly. In this Allen job, the drain had been emptying onto the siding for some time before the homeowner noticed.
Can A/C drain overflow damage siding and framing?
Yes, sustained moisture exposure from a drain overflow can swell and deteriorate masonite-type siding. If it continues long enough, it can also reach and damage the wood framing behind the siding.
How much does siding and trim reconstruction cost after water damage?
This job’s approximate cost fell under $2,500, though the price depends on how much siding, trim, and framing needs replacement. A visual inspection helps determine the actual scope.
Does reconstruction in Allen include fixing the original leak source?
Not always. In this case, the homeowner had already replaced the A/C system and cleared the drain lines before we began, so our reconstruction in Allen focused only on rebuilding the damaged siding, trim, and framing.
