In Their Words
What clients across Warren County say
Real reviews from A&S Contracting Services roofing, siding, and renovation customers near Warrenton.
“Had A&S replace the entire roof on our home after hail damage last spring. They came out fast, gave us a fair written quote, and the crew was professional from start to finish. Roof looks incredible and our insurance claim went smoothly with their documentation.”
“We needed new siding and gutters on our place outside Warrenton. A&S was the most professional of the three contractors we got quotes from — they showed up when they said they would, communicated clearly, and finished ahead of schedule. Very happy we went with them.”
“These guys did a full interior renovation — drywall, trim, paint — on a room addition at our house near Wright City. Great craftsmanship, clean job site every day, and they handled everything themselves without subbing it out. Will absolutely hire again.”
“We replaced the soffit and fascia on our older farmhouse and A&S matched everything perfectly to the existing roofline. The estimate was detailed and exactly what we paid. No surprises, no upselling. That kind of straightforward work is hard to find.”
