"We hired John Robinson to paint the entire interior, rock the living room fireplace (beautifully crafted with Austin Cave stone) 10ft to the ceiling, prep the kitchen for new cabinets and install quarter round throughout the house. The sub contractors were very good craftsmen and thatâ s what put us at ease about the project."

Diamond Decks has over 20 years combined experience in the design and construction residential industry. We inspire to satisfy thousands of Texas homeowners with creative ideas and designs. Our goal is to surround ourselves with the most creative team of honest, positive, and skilled carpenters and tradesmen in the industry. We stand by our quality craftsmanship. Our custom work and attention to detail allows us to create unique solutions for our customers. “Positive things happen to positive people.”

"Think twice before hiring this company. This review is based on how we were treated by the owner Donnie Ferguson. We hired Diamond Decks to install a patio cover in our backyard. The cover is beautiful. The material matches the house and the craftmanship of the fireplace, roof and woodwork are exactly what we wanted. Here’s where it all went wrong. The last job was to stain the concrete both existing and the new walkway we had them install. The crew did not power wash the 10-year-old concrete before staining. We contacted the project manager right away and asked why they were not power washing and he said the crew didn’t think it needed power washed. Ten years of dirt and they didn’t think it needed power washed? Prior to staining, the crew put samples of the color on the concrete and asked for approval of the color. They didn’t wait for the stain to dry but had us sign off on the color while it was wet. The certificate we signed says “Do not sign this certificate until all services have been satisfactorily performed and material supplied or goods received and found satisfactory.” Despite this warning they had us sign the certificate prior to the stain and seal being applied. Let me also point out that no one asked us what we wanted the stain to look like or guided us in any way to get the look we wanted. The stain looked nothing like we wanted so they came back and applied another color and seal and made it worse. We reached out to Donnie and let him know we were not happy with the stain. His resolution was to charge us another $10,000 to do an overlay on the two patios and then apply another stain. Donnie believed it was the old concrete that was the problem and thought we needed an overlay. We received quotes from two other companies to fix the stain. Neither company thought we needed an overlay. Instead they would remove the seal and stain and reapply the color we wanted. We again reached out to Donnie and respectfully asked for a reduction in our final payment of $7500 to fix the concrete stain. This was his reply: Absolutely not. We are experts and what we do and the color selection you picked does not need multiple coats. I do not care who you are getting your false information from. And you cannot remove foot print and terrible texture work that is in the concrete work we did not pour. The imperfections would be difficult for anyone to see because they are enhanced once the color and sealer are applied. This has one of the best sealer you can use and this is specifically why the form says DO NOT SIGN THIS FORM Unless you approve the color. It’s not an easy product to strip off hence the reason it last much longer and that’s why we use it. The balance owed is now past due $41628. I will need payment in full by the end of day or I will need to notify the attorneys that the contract breach is made. You’ve signed all the paperwork we asked of you and now you wanna insult us by telling us you want us to refund money cause you don’t like what you selected. This is the owner of the company, threatening, insulting and hostile. We of course were not in breach of contract and he knew it. They had just completed the work seven days ago. Again, think twice about hiring this company. They showed a total lack of concern about our dissatisfaction and blaming us for the results of the concrete stain. I will say that Casey, the project manager, was always professional and showed empathy for our concerns."

FAQs for addition to existing structure building service projects in San Antonio, TX

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
