Removing More Than the Mold You Can See

Dark-colored mold can spread behind walls, beneath flooring, inside cabinets, and through other porous materials. Cleaning or painting over the visible surface does not address concealed growth or the moisture supporting it.

We examine the original concern and surrounding materials to determine how far the affected area extends. Our team removes contaminated materials that cannot be restored, cleans retained surfaces, and dries the remaining structure.

Could Black Mold Be Hidden Inside Your Property?

The visible growth may represent only part of the affected area. Mold can remain concealed inside damp walls, ceilings, flooring systems, cabinets, insulation, and other enclosed spaces.

Signs professional black mold removal may be needed

Dark spots return after cleaning

Recurring growth can indicate that moisture remains or that mold extends below the visible surface.

A musty odor has no clear source

Persistent odor can come from mold behind drywall, beneath flooring, inside closets, or around cabinets.

Walls or ceilings show water damage

Stains, bubbling paint, softened drywall, or peeling finishes can point to moisture inside the assembly.

Flooring or cabinets are changing

Warped flooring, swollen baseboards, and expanded cabinet panels can develop after porous materials absorb water.

Mold appeared after a previous leak

Drywall, insulation, framing, flooring, and cabinets can support mold when they do not dry completely after water damage.

How We Remove Black Mold From Building Materials

We prepare the removal plan around the affected materials, size of the work area, moisture conditions, and how the space connects to adjoining rooms.

We inspect the affected areas

We examine the visible growth and check surrounding walls, ceilings, flooring, cabinets, closets, and other accessible materials.

We map the moisture

We take moisture readings to identify damp materials and determine whether the affected area extends beyond the visible mold.

We establish containment

We isolate the work area and operate HEPA-filtered equipment to limit the movement of dust and particles.

We remove and clean affected materials

We carefully remove materials that cannot remain, HEPA-vacuum retained surfaces, and complete detailed cleaning.

We dry and restore the area

We dry retained structural components and coordinate independent clearance testing or approved repairs when requested.

Controlled Removal From Containment Through Repairs

Black mold removal requires more than tearing out visible materials. The work area must be isolated, affected materials handled carefully, retained surfaces cleaned, and damp structural components dried.

Why property owners call our mold removal team

Inspection beyond visible growth

We check surrounding areas to determine whether mold or moisture extends into connected materials.

We isolate the removal area and use HEPA-filtered equipment during appropriate stages of the project.

Careful material handling

We remove affected porous materials in a controlled manner and clean retained structural surfaces.

Clear project communication

We explain what we find, review the proposed removal scope, and keep you informed throughout the work.

Sam and Ali were absolutely fantastic to work with. From the very beginning, they were professional, thorough, and incredibly communicative. They came out multiple times to assess the situation and provided a detailed, transparent quote that clearly outlined the scope of work—no hidden fees, no surprises. What really stood out was their honesty and the time they took to explain everything. The level of detail they provided gave us full confidence in their knowledge and capabilities. They were easy to talk to, responsive, and clearly dedicated to helping their clients understand every step of the process. If you're looking for a company that is reliable, transparent, and truly knows their stuff choose A/S general contracting. I 10/10 recommend them.

Charlene Krietzberg

The entire crew at A/S General Contracting were great! They kept me informed every step of the way. They were professional and did a great job on my restroom restoration. Magda helped me through the entire insurance process and I am so appreciative. I definitely recommend their services.

Rebecca Gomez

A/S general contractor was recommended by a friend and so glad I went with them. They were able to come in and remodel our house after a flood and it far exceeded my expectations. They turned a stressful situation to easy and stress free for us. Special shoutout to Sam, for keeping things honest and straight forward. I knew what I was getting from the get go and if I had any issues he was able to correct them within the hour. Sam is detailed oriented and you can he shows that he cares about the customers by his actions.

Chad Whitehouse

Two years after the “shoddy” work they performed we are having to completely replace the flooring. They shot pin nails into laminate flooring but that isn’t the worst part. The patchwork they used to lay a sub floor was crap. They know what they did. They all like to agree and blame the homeowner for whatever goes wrong. One tone even suggesting they because we live in a “trailer house,” the floor would never be perfect. Well now we see clearly what kind of a pieced together project they did, we now have someone who is fixing this fiasco! Don’t use them

Danette O'Quin

AS General Contacting is a great company. They repaired the water damage to my porch in a timely, professional manner. I highly recommend them to anyone who needs any type of repair!

Deborah J. Davis

Any leak damage will take time and patience. Ali, Greg and Abel were great. Good communication! Good follow through! Scheduling was clearly communicated. Every project takes time, but these guys took care of the little details. They also helped me get the most from my coverage. This is my 3rd time working with A/S Contracting. I would recommend them to anyone.

Eric Hughes

Maria Tsagalakis

Professional, patient, first class customer service, on time execution and overall great experience working with this company. Highly recommend!

Olivia Bue

We had a major water leak that required us to file a claim through our insurance company, and our plumber referred us to A/S General. From the very beginning, Greg and Sam were incredibly helpful, guiding us through the entire process and helping expedite everything with our insurance company. Greg, Sam, and their entire team were professional, thorough, and communicative every step of the way. The construction crew consistently showed up on time, worked efficiently, and always left the work area clean at the end of each day. Thanks to their attention to detail and quality craftsmanship, our home is now in even better condition than before the water leak. We highly recommend A/S General to anyone in need of home restoration or construction services. Thank you to the entire team for taking such great care of our home!

Mark Anthony Yraola

I had such a great experience working with Ali and his team. I own two salons and over the years his team has helped and guided me into the many upgrades and changes I've done thru-out the spaces. I like to stay current and hip, whether thats rearranging furniture, window treatments, fresh paint, crown mold,etc ...His team has been there to help me manage my spaces. Hard to find good communication and customer service today, your in good hands with this company

I highly recommend A/S General Contracting and will most definitely be requesting their services again. I had major water damage in my house and the repair and replacement done was outstanding.

Customer service was astonishing and they worked very quickly to get me my house back to 150%. I am beyond pleased work they did. Well made, durable and worth every penny. The service, product and overall experience was outstanding.

I just want to start of by saying that this company went an above and beyond for us to get the scope writing and administrative negotiations with our insurance.I feel we received the most money so our insurance would take care of the flood we had at our home.

Requested to do the job asap. Told Sam Abraham we have house guests coming in at the middle of the week. He sent a crew to see what needs to be done. By Monday, they started fixing the damage and late afternoon, the same day, the job was done. Sam Abraham didn't promise but he produced the result. Ben L

Had some water damage in my shower and closet due to a burst pipe leak. A/S General Contracting came in and worked with my insurance to get my shower back to peak shape. Appreciate the professionalism and communication from Sam every step of the way. When I had a question he was easily accessible. Will definitely recommend to family and friends. Special thanks to Hugo as well for the good work.

The team has been on time,quick, understanding & professional. I can say a lot of people are not like that now and days. Sam and Travis were amazing at what they do. Need more good people like them. From somebody from the military nothing makes me happier than someone that is on time and staying true to their word. Continue the good work you do gentlemen.

Sam and A/S General were great to work with. Sam was very helpful in walking us through the insurance process for our water damage and was even able to get us more money then our other contractor. Sam was always available no matter how many questions I had. I would definitely recommend this company for any restoration project and Sam is by far one of the best individuals I have had to work with.

Dark Mold Growth Across San Diego Properties

San Diego includes older homes, modern residences, condominiums, apartments, hillside properties, coastal buildings, restaurants, and commercial spaces. Their materials and ventilation conditions affect where moisture collects and mold develops.

Coastal humidity can contribute to condensation around windows, exterior walls, closets, bathrooms, and cabinets. Seasonal storms can introduce moisture through roofs, balconies, windows, exterior walls, and lower-level openings.

In apartments and mixed-use properties, water can travel through shared walls, ceilings, and flooring systems before dark-colored mold becomes visible.

Areas commonly affected by mold

Drywall and wall cavities
Ceilings and insulation
Flooring and subflooring
Bathrooms and laundry rooms
Cabinets and built-in finishes
Closets with limited ventilation
Attics and roof-adjacent materials
Window and exterior-wall areas
Shared building assemblie

Black Mold Removal FAQS

Can I identify black mold by its appearance?

No. Several species can appear black, green, brown, or gray. Laboratory analysis is required to identify a specific mold species.

Can black mold be cleaned from drywall?

Because drywall is porous, mold can affect the paper backing and gypsum beneath the visible surface. Depending on the damage, controlled removal may be more appropriate than surface cleaning.

Does black mold always need testing before removal?

No. Removal can sometimes proceed when visible mold and affected materials are clearly identified. Independent testing can be useful when species identification or documented clearance is requested.

Can I remain in the property during black mold removal?

That depends on the size and location of the work area, affected materials, containment, and how the property is occupied. We explain access restrictions before removal begins.

How long does black mold removal take?

The timeline depends on the affected area, materials requiring removal, containment, moisture conditions, drying, testing, and repairs. We provide a clearer schedule after the inspection.
