Nima is punctual and very responsive to questions. We are very happy with the new bathroom vents. We've called around asking for quotes and Nima is the only one who can do it without a major construction. We highly recommend him.

5 stars is not enough! Stephen rushed right out and patched my roof and stopped the leak. He explained everything as he was doing it, giving me best and worse case scenarios. He even went so far as to start taking down the saturated dry wall and insulation to help speed drying and prevent more mold from growing. I will definitely be using Box Construction again and referring him to all my friends.

Rating: 10/10 I had requested 2 sofa's to be picked up and be taken to the dump! One sofa was a large sleeper "L" shaped sectional and the second sofa was a studio sized "L" shaped sectional. Mr. Loera was extremely professional and responded quickly even though I am a night owl and was corresponding late at night. He was able to fit me in-in his schedule and Not only did he arrive on time but he was even a little early. Mr. Loera was very polite and nonthreatening. Easy to approach and got right to work. He wasn't pushy or try to change the price we agreed upon last minute. I would definitely Mr. Loera & James R Loera Construction; to any single females that need help moving things or to anyone looking for a reputable and trustworthy professional. I will definitely be calling Mr. Loera for future projects!

We hired Mike and Brandon at Top Knotch Flooring and Construction to re-tile our BBQ island. They were timely, reliable, and did a great job. They were detailed- oriented and took time completing the job. It's difficult to find contractors who will keep their word. Mike and Brandon did that for us.

Johnny did an amazing job repairing my damaged wooden patio cover. He gave me a very detailed estimate and even though it turned out that he had to replace several more wooden beams than originally estimated, he did not increase his charge. He is very professional and thorough and has a great positive attitude! I strongly recommend him. --DH

After looking into our project (drywalling garage and some demolition), we realized we wanted to wait on this project and save up for a better budget that would serve our needs better. However, our experience with George was very professional from the get go. He called and stopped by the very same day I posted the project. He provided an estimate on the spot, and even stopped by a day later to drop off a written estimate. Since we want our garage to serve as a gym/work area, we realized we needed a bigger budget to serve our needs and have the final project be as nice we'd like. George's professionalism left me feeling very impressed and comfortable with him. This is the type of man you could trust both inside/outside of your home, and for this reason, I'll definitely be considering George for any work my home needs in the future!

I hired Reliable Repair to remove a flight of outdoor steps and enclose the balcony (where the steps had been). I was impressed with Jose right away. He arrived a few minutes early to provide an estimate. He was very pleasant, professional and gave me a fair price. We scheduled the job for Tuesday morning and again, he was right on time. He did exactly what I asked for, he got the job done faster than I expected and it looks great. I'm very pleased with his work and I'm sure that I will be hiring him again. I highly recommend Reliable Repair!

When Chris and his father Tom built an 800sq.ft. detatched two story structure on my property in Costa Mesa. From the get go they were timely and well versed in the art of construction. The job came in on time and at the proposed budget. The overall experience was very good and I would use them again if they'd travel to Hawaii to work for me.

Had a excellent experience with BCD Construction. I have had problems in the past with contractors cancelling and just not showing up, this was absolutely not the case with BCD. They showed up on time when they said they would. All the people who worked on my job (installation of vinyl flooring and baseboards) were very nice and helpful, and went beyond to make sure things were done properly. If you want honest , professional people who get the job done right you will be happy in choosing BCD.

I had a GREAT experience with Daniel from World Class Construction! I did not know him before, but he is now my "go to " guy. I had a smaller but very difficult job with some drainage issues and he came up with good suggestions on a repair and his cost and service were great. Also had some additional drywall work done and he was also very fair and competitive. Daniel was also very professional in every aspect, from the contract to finshing the work.

I had a big project and was overwhelmed with all the different contractors i was having to hire when here comes JDA construction to the rescue. One General contractor handled all the trades at fair prices and very high quality workmanship. These boys don't play around. Completed project way ahead of schedule, highly recommended to all. Even if you have a smaller project. They do it all !! Very knowledgeable and professional and don't cut any corners. Build it once and build it right with these boys!!!!!!! I'm saving their number and using them for anything and everything i do in the future.

Octavio is absolutely the best carpenter I have ever worked with. He actually teaches carpentry as his main job & does these projects for fun! He is an absolute master of his craft & is so passionate its really inspiring. From start to finish he went above and beyond... and get this, he even suggested a way for me to save $700 on the project. Seriously, when has a construction project ever come in under budget? If you want someone you can trust who will take pride in his work & has the expertise of a true master, Octavio is your man.

I’m so glad that I found SDP Construction. They repaired significant damage done to the side of my house caused by a motor vehicle. I had an awful experience dealing with a contractor that was provided through my insurance who never showed up when scheduled or returned my phone calls. SDP were a god send. They were very responsive, professional and did great quality work. Saied was a pleasure to work with. Just a genuinely honest person that I felt I could trust. I would 100% recommend SDP for any general contracting work needing to be done.

We had jacobs construction do an expansionand remodeling of our business and we could not be more pleased. Our business had about 2500 sq ft 3500 sqft. His crew had to knock down the wall between the units, build some rooms, remodel the bathrooms, install a special floor and all sorts of other tasks. He was able to complete the job on despite a nearly impossible schedule I gave him and the quality of the work was awesome. He did not cut any corners despite the schedule. Our expanded business looks fabulous and our customers could not be more excited about our business. Jacobs construction was always extremely professional and very easy to work with. I highly recommend them.

My name is Eunice Waldenberger. I wanted my kitchen and bathroom completely done, and got estimates from three different companies. I selected Ramos & Sons Cons. Co. because it was the only one that truly listened to my concerns and what I wanted done. I was not disappointed. I selected every item installed: floor tiles, granite count, back splash, custom cabinet, even lighting fixtures, all within my price range and time frame. Other companies were asking a higher price for a lesser quality. I am delighted with the results.
