"I contacted their sales rep who worked with me over a period of a few months to set this plan in motion.  He was very helpful, honest and attentive.  I appreciated that he didn't hound us for the sale.  Once installation day came, the team showed up on time.  They were very neat, and very very polite.  We were impressed at how efficiently this team performed together.  It was clear that they had their routine down to an art. They took out the old windows and put the new ones in a very efficient manner in the middle of January!!  They worked so diligently that our house never even cooled. The windows fit and look great.  They did a nice job of cleaning up, both inside and outside the house.  And they finished all of this in one day.  Start to finish, I believe they installed everything in 6-7 hours!  I cannot say enough good things about this whole experience.  And they charged less than half the price of their local competition!  I can't wait to recommend them to my friends and family.

"Green Valley came to my rescue again! We had a leak in the house and we were not sure where it was coming from. I called Green Valley, who installed our roof 7 years ago, to see if that was the problem. They sent out a two guys (that day!) to inspect the inside and outside of the roof. They ended up finding that there was an issue with the chimney that was causing the leak and not the roof. Not only did they not charge me for the visit but they gave me a on the spot estimate to resolve the issue. They have always been great from the installation of our roof, as well as an estimate on our window replacement. They are all about customer service and it shows!!!!"

"Costly! Incorrect measurement of basement windows delayed installation by months. I had to recaulk inside and out, to reseal. Broken window-slider handle. My continuous calls for window installation yielded, no apology or price break. Once installed payment notice immediately mailed with threat of collections because contract states payment at time of completion. No follow up on warranty, servicing etc of my crawl space encapsulation as promised to me at time of signing contract."

Windows FAQs, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.

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.
