"These guys were awesome!! If you need foundation work, call them first. I have a raised foundation and it was off by 3 in. in some area's. I went with this company because they do not use contractors or sub-contractors. Everything is done by the company! I had one window break and they called me immediately about it, cleaned it up and got the plywood to cover the opening. When they gave me the quote I didn't quite have the money. I called them apprx 10 mos later to give the go ahead with the work. By that time the prices had gone up ALOT by 10K. But they honered the 1st quote because it was under a year old. And a good warranty!!"

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote.  Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

"After the large windstorm we had here in Lancaster, CA my roof suffered some major wind damage. I called them and they set me up with someone to quote us for the job. The price seemed fair and once I had signed the contract they scheduled the repair for the end of the week. The work was done well, and the employees were very professional. I was pleased with their punctuality, and the fact that they cleaned up after themselves. I would recommend Western Pacific Roofing Corp. to all my friends and family. my rof."

"Basically, they came, and he wasn't really able to do anything for us so it was a waste of money. He just kind of looked around and said, "Hmm... No. We can't do anything." We were leaking in the garage and there are several spots in our house where there are large cracks and we wanted to make sure what was going on, and he didn't do anything. He just kind of, "Well, you could replace all of this stuff and that'll be like $5,000" and I was like "You got to be kidding me." We had somebody else come out, too. I don't feel like he did anything wrong so I didn't want to post a negative post, but there wasn't also like anything positive out of it, and it felt like a giant waste of my money. But again he didn't actually give us any information other than "By the way, you have cracks in the ceiling that I could say like $5,000" which I haven't even asked him about. I think he should have been more communicative. He could've been more helpful, maybe. I didn't want to post a rating on this because it's kind of complex. He did the job, but it was not helpful. I guess, he did fine for price. I think he was on time."

"Goodfellas took care of us when we needed it! We had a pipe burst between floors in our multi-level house this summer, ruining our downstairs kitchen, and effecting some cabinetry in our upstairs kitchen. Once we got that clean-up out of the way and got the insurance claim started, we started shopping around for contractors that could help us out. We had three different estimates, but Goodfellas was the least expensive while still meeting all our needs. Our project manager Danny really set up a plan that would fix the damage, while also giving our upstairs kitchen a much needed facelift. His crew foreman Nir, and his crew—especially Arnold—was very helpful and efficient. It was easy to communicate with Nir via phone and text, and I would say I spoke to Danny via email at least a few times a week. Danny was really helpful in matching our new cabinets to the paint choice I had made for the remaining cabinets. They both made sure we were happy with each step and installment, or they fixed it until we were. We even ran into some insurance trouble midway through, putting a halt on our funds for the project. After explaining the whole nightmare to Danny, he was patient and waited with us until Nationwide could pull it together to help us finish this project. And once the final money was approved, Danny’s crew was quick to finish up the kitchen so that we could return once again to our normal lives. In short, they met our demands easily and did the project quickly and proficiently. Whenever there was a confusion or problem, it was easily communicated and handled. The crews were friendly and respectful of my family and house. Arnold went out of his way to make sure my kitchen upstairs was exactly how I wanted it, even down to giving me choice of threshold trim when he could have just slapped down any ol’ trim and I probably wouldn’t have noticed. And he always had a quick smile for my children. I would recommend this company to anyone needing work done in their home."

"I had used them before for my own house, but  not sure if they could drive all the way to Anaheim to fix my parent's driveway. They had no issue assigning a team to their place, after the work they did, I already knew a good job was expected. I gave the options to my parents, and they liked the ideas I pitched them. They did a simple driveway, nicely done and was stamped concrete."

Basement Waterproofing questions, answered by experts

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.
