What Are the Signs of Basement or Crawl Space Mold?

Do you smell a stale odor in your home? Does this odor become more prominent in the basement or crawl space? If you inspect your basement and crawl space, are you able to see mold growth on the floor, walls, around windows, or on the floor joists? These are all common signs that you have a basement and crawl space mold problem in your business or home and need to contact a professional before the issue becomes worse.

Can Mold in Your Basement or Crawl Space Affect Upstairs?

In most cases, mold problems in your basement or crawl space will affect the areas of your home above it. Air rises inside of your home which causes an upward flow of air and indoor air quality could be affected. If you do not have a central HVAC system or fans, then airflow may not be distributed properly throughout the home. Keeping your basement well ventilated and heated will help control moisture and airflow and prevent future mold growth.

How Fast Can Mold Grow After a Basement or Crawlspace Flood?

If your home or business has had moisture or flooding problems, it is likely that mold and mildew problems exist or soon will. Under the right conditions, it typically takes between 24 and 48 hours for mold to begin forming. Depending on the type of surface materials that are present, the amount of moisture, temperature, and airflow will affect the speed at which mold will grow.

The Project Manager will perform a thorough Assessment of your basement and crawl space. The Project Manager will look for signs of mold and determine the root cause of the moisture and mold issues. Mold issues require professional mitigation and cleanup services.

If it turns out that you do need basement and crawl space mold cleanup, we will provide you with a detailed estimate tailored to address the issues causing the mold problem as well as the prevention of future growth. In some cases, this can include foundation crack repair, new windows, waterproofing systems, crawl space encapsulation, spray foam insulation or dehumidifiers.

Mold remediation

I had mold remediation in my sump pump closet. They came when they said they would and were very professional. This is the second time we have used them. We used them for mold remediation in our attic at our previous house.

The technicians were prompt, respectful and thorough. They completed the attic mold remediation without disruption of the rest of my home. They even cleaned up afterwards. We are very happy with the services provided and would highly recommend them.

Laura C. Palatine, IL 60038 Mold Remediation

Mold problem in attic

Things went great! When I discovered a mold problem in my attic I gave them a call and they promptly came over and evaluated our situation. Alliance did the job while we were at work and left an air scrubber for a few days to make sure that everything was cleaned up. The level of inconvenience for us was very minimal. We were very impressed at how hard they worked with other contractors to help correct our venting issues. They seemed intent on making sure that everything was done right so that we wouldn’t have problems in the future.

Damaged drywall from leaking roof

I hired Alliance Restoration to remove the damaged drywall in my bedroom, bathroom, and laundry room due to roof leaks. The office staff was professional, prompt, and fair. The day of service the men arrived promptly. They contained the three areas very nicely and collected and cleaned all the drywall before they left. The job was done clean and there was not dust in the rest of the house. I would recommend them to anyone.

Basement mold remediation

We hired Alliance Restoration to perform mold remediation on our basement. Once they removed the drywall the crew discovered cracks in the foundation walls that we were not aware of. Alliance was able to fix them too. We are happy to recommend Alliance Restoration.

Mold removal

The sheathing on our attic was badly discolored with mold so we contacted Alliance Restoration for an estimate and removal. The estimate was reasonable and listed in detail all the work to be done. We were selling the house and was able to get onto the schedule quickly. The technicians were prompt, neat, and professional. The buyers inspected the attic and were pleased with the results.

By far best company we have worked with

Cleaned up attic mold

Alliance Restoration cleaned up the mold in our attic on the sheathing and rafters.  We found them to be very responsive and willing to take the time to explain what they were planning to do.  They cleaned up after they were complete and you would never have known they were there.  We appreciate the good work they did.

Kevin R. Arlington Heights, IL 60004

Removed mold in our attic

Alliance removed the mold in our attic and ran an air scrubber to continue to clean the air throughout the weekend.  They returned to remove the equipment and cleaned up afterwards.  They also recommended work that should be done to prevent the mold from returning and gave us a referral.

We Couldn’t Be Happier!

We couldn't be happier! Alliance performed work (crack repair and mold remediation) on our new home in early March, the week before we moved in - there were known foundation cracks, and the inspection also revealed a small amount of mold. From the first phone call, to the initial eval and quote, to the completion of work - everything was timely and professional. We elected to have them gut the small lower level (of our tri-level home), and are thankful we did - rotten floorboards and an additional crack were discovered. We were called and consulted prior to them doing some additional work that was required. The cracks were repaired, the containment process was excellent, and the work area was completely cleared of debris and was left tidy when they were finished. Then, all we had to do was wait for some torrential rain to see if the repairs worked! It is now June, and we've had 2 days of heavy rain - the type of rain that previously caused there to be water all over the lower level (this home was known to us for several years prior to purchase from a family member). I'm so thrilled to report that although our side yard is a lake (which normally meant that so was the basement), our basement is completely dry! Not a drop. We are so happy that we feel safe finishing the lower level now, and have some wonderful additional living and storage space. The cost for repair was 100% worth it. Thank you so much for everything!

Kristin H. Brookfield, IL 60513 Crack Repair & Mold Remediation

Truly professional, compassionate and detailed.

Greg Bowen's team is great. we have used them on 2 separate jobs. Truly professional, compassionate and detailed. And mold removal is all about the details. The cost kind of blew me away, but I do believe it was worth it. Hoping my daughter can get well now!
