“Keystone did a phenomenal job building my new deck. They took 100% responsibility for every aspect of the job from beginning to end – always keeping me informed. The crew who worked on deck was great – always on time, professional, considerate, hard working, and always cleaned up job site every day. The finished product is better than I imagined – structurally sound and absolutely beautiful! I love it!”

“We could not say enough good things about this company and it’s employees from the office workers to the field crew. Excellent work and very professional. We could not find another company to give us what we wanted. We were giving up hope until we found them at a Home Show. They kept us informed along the way as to their timing of each step of the job and ended up getting the work done earlier in the month, since they had an opening. They handled all the permits and all we did was have to pick out our choices of materials. They were all very attentive making it a very easy process. We had our deck boards replaced with Trek and a new aluminum railing system installed with lighting. We also had a Pergola built with a retractable awning. It has worked out so well we now are enjoying sitting out on our deck again and considering it a new room added on to our house. We would totally recommend this company and would use them again. Thank you.”

Swimming Pool Contractor FAQ's

An average size for a home swimming pool is 16x35 or 560-600 square feet. Depth varies from pool to pool and depends primarily on the owner's preference. 

Yes, a swimming pool can easily be incorporated into a deck or patio. If you'd like help with envisioning this or brainstorming, our design team is happy to help! 

Swimming pools can last quite a long time if you take care of them. In fact, both fiberglass and concrete pools have a lifetime warranty on the pool shell, and most have a 15-20 year warranty on the finish. 

The time it takes to install a pool can vary depending the complexity of the project. However, most fiberglass pools take 3-4 weeks to install while concrete pools take 2-3 months to install. 

There are a number of materials available for constructing a swimming pool, but fiberglass and concrete are usually considered the two best options. 

Anyone that ones a swimming pool and has young children should be careful to protect their children. You also need to know that there is a risk assumed with having a swimming pool. 

However, there are several things you can do to make a swimming pool more safe for children: 

1. Put a fence around your swimming pool

2. Add a safety cover if possible

3. Alarms that sound when a person or animal enters the pool.

4. Self-locking gates

5. Gradual slope from the shallow to deep end of the pool. 

Pools are fun no matter what shape they are in. And sometimes, people prefer specific shapes for certain reasons. 

However, rectangular pools are usually considered the most versatile and are the easiest to add pool accessories like water nets.
