Our Review

Editor's Rating
Editorial ReviewKeystone Homes are above average homes for the entry level to mid range home buyers. They are a smaller operation that is often overlooked by the bigger operations in Pennsylvania but you should make sure to check them out. Our mystery shopper enjoyed their website and found their customer service to be very good. This family owned business definitely seems to take pride in their work. This is a solid option for home buyers within their limited delivery range.

My Keystone is 40 years old and I still love it. It is just what I needed and still needed. Economical on heat and air conditioning. Have needed little maintance.

This family owned modular builder is the best there is! I am extremely pleased with the product, the people and the service. 5 STARS plus!!!

Vaughn Vitez from McHenry Maryland
We bought our Keystone home in 1983. Over the years of the changing seasons, we have had no problems with our home. In 2004 we added a two car garage, sunroom and enclosed entrance that has joined the two together. We have never regreted our decision to buy from Homes By Keystone. We did change the roof pitch and replaced the aluminum siding to vinyl siding to match the addition. The carpeting, all fixtures are the same and only had to repainted the walls and ceilings.Not bad for a home that has been through high winds, heavy snow, rain, and summer heat. This is a 28 year-old home that still looks great. If your looking for a quality built home, built by a professional builders, then, talk to a represenative with Home By Keystone.

Peggy Offutt from Woodsboro, MD
We added a Keystone home on the farm in 1985 and now, August 2009, the home is fitting our son's growing family and we are adding to the basic home. We are asking Keystone if they have "modular" add-on's to their original package homes?

ed antenberg from libertytown maryland
the finest home for the money bar none in terms of floor plan, comfort, and efficiency. Did a full basement under a 4 section rancher with walkout and large garage. Just love it!
