I moved in a new house with an old beat up Bathroom, I hired Prosource, left town and on my return a brand new bathroom was waiting for me. How comfortable is that? Simply Awesome!

~ David R. Hajian

After getting stood up by various companies, James of Prosource Builders came to the rescue. My home property got some serious water damage and I was in need of help. After giving me a quote he went straight to work the following day. James would send me daily updates and pictures of the progress. At the end of his work he even cleaned up after himself! I was very impressed by his work and professionalism. He is a keeper in my book!

~ Mission Fitness Center

Prosource Builders is truly incredible. It is hard to find quality and reliability in today’s environment, and James exceeded all of our hopes and expectations. We were in a jam with our kitchen cabinets falling apart because the previous handyman did a very poor job, James came over the same day to assess the situation while also driving around town to find the right solution and fix it promptly. He truly cares about his clients and is relationship driven which is truly rare in today’s market. His communication is incredible, and he is a rare find. I would recommend him to anyone that is in search of a hard working and reliable craftsman for any project around the house.

I have hired James Khatab multiple times for multiple projects, including completely replacing my roof, upgrading my central HVAC system, installing a new electrical panel (and service mast for LADWP), crown molding, kitchen cabinetry and counter tops, tile installation, bathroom remodeling, replacing my water heater, interior and exterior painting, hanging and repairing doors, and installing new windows. He represents all building trades and only hires excellent workers who meet his high standards. He has always been reasonably priced and the quality of his work exceeded my expectations. As a homeowner in West Hills for 22 years, I’ve dealt with many other licensed contractors in the LA area, with mixed results. Now that I’ve found Prosource Builders, I would never call anyone else.

We have spent the last couple of months exposing and educating regional construction and regulatory professionals on the serious problems concrete washout poses to the environment and the solution we will be providing them. They are very receptive and are elated to finally have a solution to a problem that has been plaguing the industry for years.

~ Rich Jeffrey, President of CWS Colorado, LLC.

Using Concrete Washout Systems allows WOC to easily contain our washout materials and keep our outdoor exhibit space free of concrete slurry produced by various exhibitor demonstrations. Substantial quantities of concrete waste water are generated in the Outdoor Exhibit Area. Concrete Washout Systems provides a critical service in containing waste water enabling us to comply with WOC's no discharge policy. Managing waste water is always a challenge at the show, but this year Concrete Washout Systems is making the job much easier.

~ Sue Basham, World of Concrete Outdoor Exhibit Manager.

Your service is fantastic! The bins reduce SWPPP concerns and are a very good BMP measure to employ. We don't have any more headaches because of clean up and it has reduced our costs as well.

~ Pawell Salamonik, Superintendent - AG Spanos.

The CWS system solves one of the construction industries greatest compliance problems of concrete washout entering streets and storm drains. Not only does it solve a major compliance issue, but it also creates a much needed recycled product for the construction industry. As a consultant, we look for practices that are good for business and good for the environment. The CWS system meets both criteria.

The Concrete Washout Bin virtually eliminated our concerns over SWPPP (Storm Water Pollution Prevention Plans) violations relating to concrete washout.

We had been searching for a company to complete some concrete work for some time. Not knowing all of the concrete terminology we had a hard time finding someone who would complete exactly what we had been looking to have done and not charge us an incredibly high rate! Then we found Gem Concrete Polishing! Not only were they extremely helpful in explaining the unfamiliar terminology and processes to us, they were so kind and amazing to work with!

~ Alicia L. -Vacaville Skating Rink Project

After using Gem Concrete Polishing to improve the floors of my business, I am convinced that it is the top polishing service in Northern California. They were generous enough to fit my request into their schedule very last minute. They were also extremely easy to communicate with throughout the entire process. The end result was even better than I had anticipated and it was finished quickly too. I am grateful for the work that they did and pleased with the entire experience!

~ Kento M. -Berkeley Art Studio Project

Gem Concrete Polishing managed to turn our nasty, 50-year-old condo concrete slab into a floor more beautiful and durable than I ever thought I'd own. And they did it under budget and on time. Absolutely AWESOME customer service, Tomasi and his crew, and Amy in the business office, demonstrated consistent professionalism and responsiveness. Plus the pricing was VERY competitive. HIGHLY RECOMMEND!!

~ Ellen L. -Walnut Creek Residential Project

"Wow wow wow !!! I can't say enough about my amazing experience with Gem Concrete. The customer service was excellent- the team was fantastic and my floors turned out stunning!!! Super quick and hardworking team with no surprises! The results exceeded my expectations. I would recommend them 100%. Thank you gem Concrete. You are truly the best!"

~ Nicole. Y. -Benicia Retail Store Project

Tomasi and his crew did an outstanding job polishing and staining our concrete garage floors. It absolutely transformed the space. The result looks so much more elegant than an epoxy finish and ended up costing less as well. We highly recommend GEM.
