"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."

"They came out and gave us a quote last fall, then we did the roof this spring. They added a ridge vent. Overall, I found them excellent to work with. They delivered documentation for our "5 Star Certainteed Warrenty" as promised. They seemed much more straight forward/honest than some of the other quotes I got. I would recommend getting a quote from them if you are replacing a roof"

"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%."

"Excellent service and support, and I could not recommend them enough. Our insurance provider was dragging their feet for months and declining us a new roof when Brian from Coldstream was confident that our entire roof needed to be replaced. He worked with us in gathering the necessary pictures/information to have our insurance company send out another agent to take a look at everything. Their second agent agreed that we indeed did need a new roof, and updated our claim. Without Brian and Colstream, we would not have been able to get a new roof from the hail damage in March of 2024 which we definitely needed. Thank you guys again for the consistent support and patience!"

"We hired H@F to resolve storm damage to our roof/siding from 2025 spring hailstorms. Our project managers name is Reggie Trankle. From start to finish Reggie proved to be outstanding. He assisted us with coordination requirements between the insurance company and contractor, he ensured the work performed was done professionally, he always made himself available for questions, and he kept a positive and professional demeanor from the start of the project to the completion of the project. The siding and roof installation turned out great. We are planning to update our siding on the North side of the house next year and will insist to have Reggie manage that and all future roof/siding projects at our residence.

Siding questions, answered by experts

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.

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?

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, 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?

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.
