We are not a big company that you have to go through all the phone calls. Owner Andy Zhang will be the one to answer the phone, provide you the bid, and supervise and inspect the work before finish. We are so confident in our work, quality, and over all experience that we don't need any money down. Our customers don't pay us anything until the work is done and customer is happy! For a house on the market, in most cases, we allow owner pay the full bill through escrow at closing. We pride ourselves in treating every customer with honestly.We looking forward to hear and serve you soon!

"Gauge is a Representative who puts his Clients first. He reminds me, of a younger me.

"Wow. I have used Classic for 8 years, both for insulation and pest control. They were great to work with and did a consistently good job for a reasonable fee. As a text from them today requested, I called to reschedule a service call. The person who answered identified himself as the owner, and indicated he was “back” because he didn’t like the way the company was being run. Because I wanted my service to include a crawlspace inspection of the rodent traps that they put in - something that is part of the service they have always done — and that I pay for — said I was being too rigid and he didn’t want me as a customer. Again, wow."

"At every step along the way they were thorough and professional. The estimator provided a very detailed scope and quote and patiently answered my questions. The installation crew was quick, efficient, friendly, and were so meticulous with their prep that up you couldn't even tell they were here after they left. I also appreciated the "after-photos" they sent me, it looks great!"

Basement Waterproofing questions, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

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.
