A Sunroom Addition Is Great Alternative To A Full Room Addition

Some homeowners call them sunroom additions, others call them extensions, yet others call them sun room bump-outs. Regardless of their “formal” name designation, the truth is it’s a great way to add additional space to your home’s floor plan, while providing a new level of excitement.

I used 21 Century Services for a basement remodel. They were excellent! Made great suggestions, without being overbearing. Not only were the sales team nice , but the office was easy, welcoming, and the workers were VERY knowledgeable. The end result is fantastic!!!! I already have my next project scheduled with them for the master bathroom.

This company did a great job with finding the cause of my roof leak, when three other contractors could not find the cause during their inspection. 21 Century Home Services did a dye test to find the leak; it was a gap between where the upper and lower parts of the roof met, and the gutter needed an adjustment. The company also replaced the molded and rotted dry wall. 21 Century passed my check with the Better Business Bureau and it has state licenses in the DMV. They were prompt and courteous. I'm very happy!
