Where high quality, competitive pricing and excellent customer service are key components of everything we do. Bay Area Rodent Solutions provides quality service to the entire Bay Area. We specialize in rodent clean-ups, sanitation, inspections, rodent exclusion and repairs. You can count on Bay Area Rodent Solutions for a service customized to your needs.

"Bay Area Rodent failed on all of this work. Background: Our home had cold tile floors in the winter time. We called on ‘Bay Area Rodent’ in 2015 to come up with a solution and possibly change out the floor joist insulation. “Solution”: The company sales person came out in and provided an estimate to 1) replace our existing R11X16 insulation with ‘encapsulated insulation’ R19X16 and also 2) install an 8 mil vapor barrier to the flooring in our crawl space, and 3) perform a cleanup service. The salesperson claimed that this vapor barrier would reduce the cold up above on our tile floors. In addition, the estimate called for “cleanup service,” to cleanup some large debris on the crawl space dirt, that I wanted removed. Experience: The workers arrived at our house and and left within a few hours. When I needed to go into the crawlspace a few months later, I checked on and was appalled by the work that Bay Area Rodent did, failing on every single item of their work. “Install 8 mil vapor barrier to the flooring in the front crawl space.” What we got: The workers basically laid down on the dirt undersized 4 mil plastic and also missed an entire corner of the crawlspace. "Cleanup & Sub-flooring insulation & cleanup service." What we got: No Cleanup, not one bit. There were still large, abandoned pieces of plumbing and duct work left right on the dirt, and they covered this debris with the new vapor barrier! I noticed this immediately when crawling underneath. Install R19x16 Encapsulated fiberglass insulation to the sub-flooring. The insulation installed was NOT encapsulated but cheap, loose insulation which was already sagging to the crawl space dirt in many places. I contacted the company about the problems to get someone to fix these issues. Two weeks later, they sent someone out. They replaced the new insulation with the correct encapsulated insulation and removed some of the debris, great! However, they failed again with the vapor barrier install! Instead of removing the undersized 4MIL vapor barrier, they DOUBLED UP and laid down a SECOND layer of 4MIL vapor barrier, on top of the existing one. My crawl space became totally unusable, as there was not plastic strewn everywhere, making it difficult to even navigate underneath my home. Eventually, they came out and fixed this problem, and added a single layer of plastic, however the worst kicker was about to ensue. A few years later, I was underneath our home and noticed that there is white (mold?) fungal growth everywhere underneath this vapor barrier! This was horrifying to see and when I called Stanley from Bay Area Rodent, he tried blaming this on plumbing problems. While our new home, new plumbing and drains did have an issue at one time, we quickly repaired it. Experts looked at their problems and stated that the cause in fact of the moisture, is from water runoff on adjacent hillsides during the winter wet months. This work has resulted in us having to hire numerous mold experts to test and remediate this company’s terrible work. One professional contractors commented that the work of Bay Area Rodent was the worst that he had seen of anyone in his 20 years career. I am extremely dissatisfied with this work and for their proposed solution and advise you also to steer clear."

Mold Testing and Remediation questions, answered by experts

Mold can greatly impact your home's appraisal and lower your selling price if your home's on the market. Home appraisers take mold into account when figuring out a property's overall value. Mold will lower your home's price because it poses a health risk to household members and can compromise the structural integrity of the house. Mold will require remediation, which in extreme cases can be costly, so that is factored into your home's appraisal as well.

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.

If you need mold remediation, you’re probably looking at a bill of a couple thousand dollars or more. Sometimes, though, your homeowner’s insurance policy may cover some or all of the costs of the remediation. If the black mold forms because of a covered event, such as a storm that damages your roof, and causes leaking or flooding in the basement, it’s possible the policy also covers mold remediation. It never hurts to ask your insurance company if it will cover the cost of black mold remediation.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.
