"Tom responded quickly and gave me an estimate on installing two small windows on each side of my fireplace. He said it would take a month for the order and that's exactly what it was. My schedule didn't allow him to come out during the week so he came on a Saturday morning to install windows. He did a great job, cleaned up inside and out and the windows look great. I may consider installing an egress window and I would definitely use Tom's company."

"Ray the owner was on time, worked fast and did a great job. Our house will sell better because of our sparkling windows. He was friendly and even washed the two little windows on our shed for no charge that were not included in the bid.Our bid also included cleaning out our window wells and cleaning those windows. He did an excellent job. His prices are low. He is a veteran and hires veterans in his business. I would definitely recommend this company for windows and gutter cleaning."

Windows FAQs, answered by experts

Having a professional caulk your windows will cost you around $50 to $70 per window (or $1.25 to $4 per linear foot), including labor. However, caulking is one of the easiest DIYs there is, and you’ll save a lot of money by getting the supplies and doing it yourself. You’ll only pay $0.05 to $0.20 per linear foot if you DIY this one. Finally, different types of caulk don’t vary too much in price, with most tubes costing no more than $15 apiece (but typically only $3 to $10) at the most. 

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

Yes, replacing windows can boost your home’s resale value by improving its curb appeal, energy efficiency, and comfort. The return on investment (ROI) varies depending on the types of windows you install, but most homeowners see an ROI of around 60% to 70% of the cost of the window installation, according to the Remodeling 2024 Cost vs. Value Report. 

On average, bay windows are three times as expensive as a standard double-hung window, so up-front cost is a major drawback. They also let in more natural light than most other types of windows, which can be a positive thing, but it can also lead to more aggressive fading and UV damage to furniture and flooring. Larger windows allow for more heat transfer, so bay windows tend to be less energy-efficient due to their size. Finally, window treatments for bay windows can be more challenging to find, and they’re more expensive than those you’d place over standard-sized windows.

Garden windows can add value to your home and are an attractive feature for potential homebuyers. These windows add a custom look to your home and usable shelf space for homeowners with a green thumb. You’ll likely recoup your investment when it comes time to sell.
