"We had excellent experience with Alpha Structural. Charlie Rosenkranz came to see the property and advice. He checked the structures all around and looked in the basement as far as possible beyond the ducts that were filling up the space and would require tunneling to get to some areas under the building. Communication was excellent. He's knowledgeable and experienced. We appreciated his professional no pressure approach and answering our questions. The front main duplex needed Seismic Retrofit; it wasn't bolted and had cripple walls. There were suspect areas in the foundations that would have to be tested when bolting, to see if the concrete is in good shape. After we agreed to their proposal have the work done we scheduled a range date. They had to submit to the city plans for a permit to do the work and wait for the permit to be issued. While doing the retrofit we found out that the foundation in the front corner was damaged and that the building has sunken and was not level at that corner. Charlie worked out the details and bid for the additional work of Partial Foundation Replacement, Posts/piers, and Jack Lift the corner to level it. He explained the details and what's involved to my satisfaction. Alpha obtained the permit for the work and proceeded. The work crew did excellent work. Jose Morales was the Project Supervisor. They completed the work at a good pace, including the delay for the additional work permit, without complications or complaints from the neighbors. The place was left clean. The work was approved in the inspection which they requested and scheduled with the city. The communication with everyone at the office was also very good. We're very pleased with the experience."

"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"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!"

"Perfect!!! We originally d to repaint the whole house. Since that was out of our budget, we asked Tony to touch up our walls. When he finished, it looked like we had brand-new walls!!! Although it's the same beige color we already had, they look spectacular!!! He did the whole house in about 6hrs."

"They coated our roof with something like clear plastic. The product is called elastomeric. We are very happy with everything they did. We have already had them back to put in some downspouts. They also cleaned the gutters. I would use them again and recommend their service."

Basement Waterproofing questions, answered by experts

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
