I used Keystone to replace a very aging deck and patio with a larger new deck and stamped concrete patio. We also did a pavilion over the patio.

Keystone couldn’t have been more helpful and professional. From the initial consultation through design and all the construction work.

Yes, you will find cheaper contractors out there, but you 100% get what you pay for. The quality of the workmanship, the professionalism & the ease of them handling all the scheduling and multiple contractors through the streamlined process made it all worth it.

I have to give a shout out to Elmer, Jason & Mark who were here almost the whole time and frankly made the project so much easier. From their expertise to their eye for design and ideas for solving issues. I couldn’t recommend this main team any more!

- Christopher

We had a very good experience with Keystone. They did an awesome job, and they are very personable and listen to your needs. They were very thoughtful and remembering our daughters birthday, and our son when he was in a motorcycle accident. Matt and his crew did an outstanding job!!

- Happy

The builders were very efficient and professional. We had a very smooth and easy experience during the whole build phase and were informed of the updates at each stage. I would highly recommend Keystone Custom Decks to anyone looking for good quality and professionalism.

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.
