"Clifton Contracting made the whole process so easy from planning to completion. We are thrilled with the window and the complete change in our basement. We chose a larger Anderson window and an upgraded Rockwell window well. No other estimates could match them."

"I am very pleased with the communication of this company. I reached out to them at a job site and met Leaha's their project manager. The properly got me setup for an estimate of services. I did decide to replace 4 front windows. Deposit was easy to make. Windows came in timely. Yesterday my project manager was also Leah who came first advised me what was going to happen, whom was coming and when. My window team came, two great guys that amazed me how quick they got my windows out. They were upmost polite and respectful of my home and myself. Very little dust and they cleaned up everything. My windows were put in 1982 and I had cracks and they were unsafe. This team worked wonders.....new easy to be clean tilt in windows ...even easy for a woman to move. The window guys the caulking is the best Ive ever seen....so sealed and straight. The went over how to remove screens, clean windows. Kudos to the entire team. Project Manager Leaha drove back...spoke with me, inspected"

Work included constructing a temporary load bearing wall to support the ceiling and roof. The old sliding glass doors and existing header were removed without disturbing the exterior stucco siding.

A LVL beam replaced the old header and new center opening sliding doors were installed.

The workers showed expertise and care during the process. They effectively controlled dust, protected the interior surfaces including walls, ceiling and carpeting, 

It is also worth noting that Tim Whiting was able to obtain new sliding glass doors which perfectly matched other doors and windows of my home. 

I am very happy with Whiting Company's work.

"We are overall pleased with the install. However, the guys who installed them left broken glass on my bedroom door that I stepped on. Also, the caulk around the outside could have been smoothed out. Other than that, it was all good."

"During the initial visit, Bob, a master carpenter, provided a thorough explanation of the options available for installation of crown moulding to in part address a crack near the ceiling/wall joint, and submitted a prompt estimate. On the day of installation, Bob returned with Alfredo, an assistant carpenter. They did an outstanding job installing the crown moulding. From set-up, to installation, to clean-up, their work was exceptionally professional. We are very pleased with the final result."

Glaziers FAQs, answered by experts

Before starting glass and mirror service projects, verify your contractor holds a valid state license. Request a written contract detailing the start dates, project scope, and payment schedule. Check with local Frederick authorities to see if your work requires a permit. If you live in a historic district or a community with a homeowners association, secure architectural approval early. Finally, schedule exterior work during warmer months to ensure proper sealant curing.

Helpful?

Older homes in Frederick feature non-standard window openings that require custom glass fabrication. Modifying openings in historic brick masonry walls adds significant complexity and requires structural assessments. If you live in a downtown rowhouse, shared party walls restrict side-facing window modifications. Replacing glass in finished basements triggers state code upgrades for egress windows. Inspect older wood frames with storm windows carefully to prevent trapped moisture and wood rot.

Helpful?

Treat broken exterior windows or doors as emergencies, as cold MD winters and humid summers expose your home to moisture and rapid temperature loss. Address cracked safety glass in shower enclosures or low windows immediately to prevent serious injuries. You can schedule cosmetic issues like fogged insulated panes or minor mirror delamination for a later date, provided the glass remains securely fastened to the wall or frame.

Helpful?

Homeowners planning glass and mirror service projects in older Frederick neighborhoods must follow historic preservation rules, which restrict changes to window configurations and glass visibility. You must also ensure your contractor follows state lead-safe work practices if your home predates 1978. Severe weather events like hail will cause sudden spikes in local service demand, so book your project early. Confirm your contractor follows state guidelines for safe material disposal.

Helpful?

When comparing quotes for glass and mirror service, watch out for professionals who cannot provide proof of a state license or liability insurance. MD law requires both. Another red flag is a quote that omits required building permits for structural work. A reliable contractor will also specify which building codes apply to your project. Avoid anyone who dismisses your questions about safety standards or local building codes.
