Best window pros near Grantsville, MD

Q: What time of year is best to repair windows?

• <div><p>Most homeowners prefer to service their windows during the spring or fall when temperatures are the most bearable, and having large openings in your wall won&rsquo;t drastically increase your heating and cooling bills. However, while these seasons are the most convenient, you&rsquo;ll also tend to pay more for window repair due to the increased demand. If you want to reduce labor costs, consider making window repairs in the off-seasons. Avoid waiting until the heart of winter to do repairs, though, as you could run into leaks and heat loss issues.</p></div>

Q: Are triple-pane windows more expensive?

• <div><p>Yes, triple-pane glass windows cost more than double or single-pane windows. You&rsquo;ll eventually get that money back in energy savings. Depending on how much you pay for the installation, you could recoup your costs in 10 to 20 years. Triple-pane windows have extra layers of glass, which improve insulation and help save money in long-term heating and cooling costs. </p></div>

Q: Is a casement window left or right opening?

• <div><p>Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you&rsquo;ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you&rsquo;re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.</p></div>

Q: What is a good U-factor for windows?

• <div><p>A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.</p></div>

Q: Are glass block windows a fire hazard?

• <div><p>Glass block windows aren&rsquo;t fire hazards; fire-rated glass block windows can increase your home&rsquo;s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home&rsquo;s safety in the event of a fire.</p></div>
