"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"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!"

"My 23 years old tile roof need to be replaced due to poor quality material used by previous local roofer. After search through 6 estimates, I pick Tony's bid because he listen to my concern and his prices seems fair. Normally roofing job starts in April or May, after the raining season, but our roof was leaking in several spots and Tony and Tino (the roofer) started the project in February. With the wettest raining season in recent memory in LA, it was a challenge to work on roof during the break between rain storms, but Tony and Tino's crew pull through the challenge. During the process, Tino also points out several issues with our chimney and he was able to do a thural repair and painting while he was up on the roof. As with any construction project, we encounter areas that need extra work and Tony was very easy to talk to and we were able to reach a reasonable price for the extra work. The only complaint I have about the whole project is that during the project, the crew allow the dirt got into my gutter and the cleaning process was not as thural as I'll like. Overall, I am very pleased with our roof project with OM Construction. Tony is very responsive during the process and address my concern very quickly. Tino's experience and attention to detail make me feel confident about the quality of our roof job."

"I would definitely recommend Thomas Parks.  He and his team arrived on time, and completed the job of cleaning my gutters in a most professional and respectful manner.  Mr. Parks explained to me in detail all of what he would be doing and why.  He even went above and beyond.  (Note: It was Mr. Parks who originally installed some of my ground gutters more than a decade ago.)
After doing business with Mr. Parks that day, I hired him to do my Roof Waterproofing with Kool-Seal Coating.  Again, I was very pleased with Mr. Parks' work.  I would enthusiastically hire him again for future work on my house.  In fact, he and I have talked about putting a new roof on my shed out back.  Thank you, Thomas Parks.  I look forward to working with you again soon.

"I was stunned at how well this project was done. Gil, the owner, showed up for the estimate on time, submitted a proposal the same day, and graciously allowed my nervous additions to the contract, which was signed and sealed on day two, the work began two days later and was completed all in the same week! The attention to detail was remarkable and his attitude was very comforting. GM Pacific Pro is definitely going to be my go-to contractor for future projects."

Basement Waterproofing FAQs, answered by experts

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road.
