"Very professional yet down to earth. Best price I found with great quality work. Answered every question I had and gave me a great sense of comfort throughout the whole process. Very time efficient. Replaced 14 windows, added a bay window, replaced 2 sliding glass doors, and replaced an existing garage door with a 4-panel sliding glass door. Only took 2 and a half days!"

"H&F Exteriors was awarded a contract in July 2023 to replace porches of my daughter's house (front - partial and back - complete) in St Louis. When initially meeting with H&F's Project Manager, Phillip Raphael, I was impressed with his understanding of what we wanted done. It was clearly reflected in the scope of their bid (compared to other contractors) as well as the schematics which used existing pictures of the porch areas with overlays of planned construction. Less than a week after contract award, he set up a group text with himself, me, my daughter and his Production Team. I have dealt with many contractors - both personally and professionally - and must say the communication throughout the entire project was as good as anything I have experienced. Within a month, the Production Team assumed the lead and provided regular updates on material delivery and construction timing. Phillip continued to touch base periodically as well to ensure things were moving forward satisfactorily. Since I live out-of-town from where the work was being done, he and his Team coordinated everything with my daughter and kept me in the loop on progress. During construction, there were a couple issues my daughter brought to their attention and they were quickly addressed to her satisfaction. At the end of the job, a punch list of a few remaining items was completed, all extra materials were removed and the jobsite was cleaned up without any follow-up needed by my daughter. Needless to say, we were extremely pleased with H&F and will definitely be including them on bids for any future exterior improvements."

"I bought a home and the seller used Craig at Pane in the Glass to repair the broken thermal seal on a rear door. I was so pleased with the work that I used him to repair three windows in the house I sold as part of the remedy for my sold home inspection. I would recommend this company and Craig without reservation"

Window Door Contractors questions, answered by experts

In O'Fallon, you can address small window screen repair issues by using a screen patch kit for tiny tears or applying a dab of clear adhesive for pinholes. When tightening loose screens, gently roll the spline to avoid stretching. Always wear gloves and safety glasses, especially when trimming mesh. Choose a calm, dry day for repairs, and avoid working near electrical lines or during high humidity to prevent accidents.

Helpful?

For screen repair in O'Fallon, opt for fiberglass mesh for its flexibility and resistance to local weather changes. Pet-resistant mesh is ideal for homes with animals, while solar screens help reduce heat on west-facing windows. Aluminum frames offer durability against MO’s temperature swings. Use stainless steel fasteners to prevent rust, and select a UV-resistant spline to ensure your repairs last through the region’s sunny and humid conditions.

Helpful?

In O'Fallon, screen repair can influence your home’s airflow, especially if you rely on natural ventilation during humid summers. Replacing screens may require adjusting window or door hardware, which could affect how weatherstripping seals out moisture. If you have window alarms or sensors, double-check that repairs don’t disrupt their alignment. For screened-in porches, updated screens can also improve comfort by reducing pollen and debris entry.

Helpful?

In O'Fallon, common mistakes include using indoor mesh for outdoor window screen repair, cutting mesh too short, or skipping a thorough cleaning before installation. Homeowners sometimes overlook the importance of matching mesh size to local insect types. Attempting repairs in high humidity can cause materials to stretch or warp. Not checking for local permit requirements on large porch enclosures is another oversight that can delay your project.

Helpful?

In O'Fallon, screen repairs can impact your home’s airflow, energy efficiency, and moisture control. If you notice repeated screen damage, window condensation, or difficulty opening windows, it may indicate issues like foundation settling or excessive humidity. After repairs, test window sensors if you have a security system. If multiple screens show problems, consult a local screen repair professional to check for underlying home issues.
