"Friendly servicer. However, had a bit of sticker shock with air sampling. Was told it was $160 per sample but it wasn?t clear until she finished that the total would be $320 (a control sample target sample). It would have been better to clearly quote the expected total. "

Experts with water, mold and fire restoration services. Our team has over 10+ years of experience and is certified with IICRC which is the firm that sets the standards for remediation. Every team member must pass a background check and a drug test prior to employment. Our goal is to ensure our customers are completely satisfied and we leave their home cleaner than when we started the job.

"Who would think that having mold removed from my crawl space would be such a positive experience. I contacted Restoration 1 through Angi's list and they were prompt in coming to my house to assess the damage . They provided pictures and videos of the damage. All the way through the remediation and eventual clearance of the mold was done with the upmost professionalism. I was updated daily by Janny Ferrer (CEO) and there were no surprises awaiting me when I return to the residence. The quality of work and reasonable price was way above my expectations. The three technicians I would like to personally thank are Jose, Bryan and Jake. They did an awesome job. I would recommend this company hands down to anyone having water damage to their home. What a pleasure working with such a professional and caring company as Restoration 1. Thank you!"

Mold Testing and Remediation questions, answered by experts

Water damage doesn’t always cause mold and wood rot, but it can. Both mold and wood rot require moisture in the wood to form, so water damage that continues to leave water or moisture behind can lead to both issues. Water damage and mold often go hand-in-hand, but you can prevent mold growth after water damage by addressing the source of moisture and drying out the area quickly. The same goes for wood rot. The longer you let water damage go, the higher the risk of mold and rot.

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.

Yes, drywall mud can get moldy—though the presence of moisture is required for this to happen. That’s why the best way to keep your powdered drywall mud fresh for as long as possible is to keep it in dry storage conditions. If you live in a humid area, it might not make sense to stockpile a lot of powdered drywall mud before you’re ready to use it. As for premixed drywall mud, avoid opening the container until you’re ready to use it—and don’t expect it to last longer than six months.

While home mold tests can provide a simple identification of mold presence, they lack accuracy and reliability. These kits may detect mold spores but can't pinpoint the source or identify the type. Professional testing, combined with an inspection, is more comprehensive and leads to actionable next steps. 

Fiber cement siding is resistant to mold and mildew, so it won’t be as affected by these problems as something like wood siding. However, damage to your siding or improper installation can still lead to water getting behind your siding, in which case, mold can grow behind it and damage other building materials. Contact a siding repair professional if you suspect you have a leak.
