"A&W representatives were very professional and provided us with a clear explanation of the damage and the options for repair. A&W worked directly with our home insurance company to verify the full cost of the roof replacement and that it would be fully covered under our insurance policy. The roof was replaced in one day. Their was a minor issue with the quality of the fascia that was replaced on one side of the house but it was resolved satisfactorily in a timely manner. I would not hesitate to recommend A&W to anyone needing roof repair work."

"Crew arrived on time; foreman asked me to show him exactly what I wanted replaced, redone and repaired and done. Showed him where everything was, old siding, new door, where to make the opening for the new door, and where the places where that needed replacement siding. They got to work in a timely fashion and if there was any question, the foreman came to me and asked to make sure they were doing what I wanted done. Crew stayed all day to get the job done. The foreman returned the next day to fix 2 replacement spot, they had not gotten to on the previous day. Did a great job, looks great and the foreman was adamant that I was satisfied that they had done everything that I had asked to be done.  The siding looks great and so does the new door. Good work."

"Justin responded to my request to repair wind damage on our siding. It wasn’t a big job but took the time to fit us in because we were concerned about possible water damage. He bid a fair price and completely repaired the damage and explained what was involved. We will use him again and share with friends. Thanks!"

"They also installed new guttering with screening, replaced a rotted post on my front porch and did some repairs on my siding. They did it all in a few days. All crews were hard-working and polite. They cleaned up better than expected. I trusted Mark from the get-go because he was very thorough and has high ethics. I recommend 100%."

Siding questions, answered by experts

In O'Fallon, even minor cracks, gaps, or peeling caulk can quickly worsen due to humidity and temperature swings. Watch for water stains, warped panels, or sagging sections—these may point to hidden moisture problems. Gaps at corners or along seams can invite pests and further damage. Addressing these exterior maintenance issues early helps prevent costly repairs and safeguards your home’s structure.

Helpful?

After siding installation in O'Fallon, take clear photos of the finished exterior for your records and inspect all seams, trim, and caulking for completeness. Test outdoor fixtures and ensure vents are unobstructed. Each spring and fall, check for weather-related damage and clean siding with a gentle power wash. Keep warranty documents accessible and schedule periodic exterior maintenance checks to address minor issues before they escalate.

Helpful?

In O'Fallon, be cautious of siding quotes that are significantly lower than others, as this may signal shortcuts or subpar materials. Avoid contractors who push for full payment upfront, offer only cash transactions, or provide vague, incomplete contracts. Make sure professionals are familiar with O'Fallon’s climate and building codes, and always insist on a detailed written estimate, local references, and a verifiable business address before proceeding.

Helpful?

In O'Fallon, fading, cracking, or warping on your siding often signals it’s time for attention. Look for chalky residue, loose or missing panels after storms, or increased energy bills—these can indicate insulation issues. If your siding is over 20 years old, or you notice drafts, moisture inside, or pest activity, it’s smart to schedule a professional exterior inspection soon.

Helpful?

New siding in O'Fallon enhances your home’s energy efficiency by improving insulation and minimizing drafts, which helps maintain comfortable indoor temperatures year-round. Quality siding also protects against moisture intrusion and pests, reduces outside noise, and boosts curb appeal. These improvements make your living space quieter, healthier, and more resilient to Missouri’s changing weather, while also supporting long-term exterior maintenance.
