Professional Moisture Control for Damp Properties

Removing visible water does not mean every affected material is dry. Moisture can remain inside drywall, flooring, framing, cabinets, insulation, and enclosed structural areas.

Professional dehumidifiers remove water vapor from the air and support evaporation from damp building materials. We evaluate the property, select equipment for the affected space, and track moisture levels throughout the drying process.

Is Excess Moisture Remaining Inside Your Property?

High humidity is not always easy to see. Damp odors, surface condensation, and changes in building materials can indicate that moisture remains in the air or structure.

Signs professional dehumidification may be needed

Drying is taking too long

Fans alone may not remove enough moisture when the surrounding air is already humid. Professional dehumidification can support a more controlled drying environment.

The property feels humid or uncomfortable

Heavy or damp indoor air can indicate that the space is holding more moisture than it can release naturally.

Condensation develops indoors

Water collecting on windows, walls, vents, or other surfaces can indicate elevated humidity or temperature differences within the property.

A musty odor remains after water damage

Persistent odors can come from wet materials that have not dried completely.

Flooring, cabinets, or trim are swelling

Warped flooring, separating baseboards, and expanded cabinet panels can develop when porous materials absorb moisture.

How Professional Dehumidification Works

We create a drying plan based on the affected space, materials, moisture readings, and indoor conditions. Equipment is monitored and adjusted as the property dries.

We inspect the affected areas

We ask what caused the moisture concern, when it began, and which rooms or materials appear damp.

We take moisture and humidity readings

We evaluate the indoor conditions and check affected walls, ceilings, flooring, cabinets, and structural materials.

We prepare the drying area

We identify the areas requiring dehumidification and determine whether containment, air movement, or damaged-material removal is needed.

We install drying equipment

We position commercial dehumidifiers and air movers based on the size, layout, and moisture conditions of the affected space.

We monitor drying progress

We take follow-up readings, adjust the equipment when needed, and remove it after the affected materials reach the established drying goals.

Drying Decisions Based on Moisture Readings

Professional drying should be based on the property’s condition rather than a fixed equipment schedule. We use moisture and humidity readings to guide equipment placement and monitor progress.

Why property owners call our drying team

Commercial drying equipment

We use professional dehumidifiers and air movers designed for water-damaged structures and larger affected areas.

Careful moisture detection

We inspect visible and surrounding materials to determine where moisture remains.

Equipment selected for the space

We consider the affected area, materials, layout, and indoor conditions when preparing the drying plan.

Ongoing drying documentation

We track moisture conditions during the project and adjust the equipment when readings show that changes are needed.

Restoration and repairs available

When water damage has affected building materials, we can coordinate removal, drying, cleaning, and approved property repairs.

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.

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 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 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.

How San Diego’s Climate Affects Indoor Moisture

San Diego properties experience different moisture conditions depending on their location, ventilation, construction, and recent water exposure. Coastal areas can experience marine humidity and condensation, while inland buildings may hold heat and moisture inside enclosed rooms.

Seasonal storms can introduce water through roofs, windows, exterior walls, and lower-level areas. Older properties may contain plaster walls, wood flooring, and enclosed cavities that dry differently from modern materials.

Condominiums, apartments, and commercial properties can also have shared walls, ceiling assemblies, and limited access points. We consider these conditions when determining equipment placement and monitoring the drying process.

Materials that often require moisture monitoring

Drywall and plaster
Wood framing
Flooring and subflooring
Ceiling materials
Insulation
Cabinets and built-in finishes
Baseboards and trim
Attic materials
Crawl-space materials

Dehumidification Services FAQS

What does a professional dehumidifier do?

A professional dehumidifier removes water vapor from the air. This creates conditions that help moisture evaporate from damp walls, flooring, framing, and other building materials.

Is a dehumidifier enough to dry water damage?

Not always. Effective structural drying can also require water extraction, air movement, removal of damaged materials, and moisture monitoring. We determine which methods are appropriate after inspecting the affected space.

How long will dehumidification equipment need to operate?

The timeline depends on the amount of moisture, affected materials, size of the space, indoor conditions, and how quickly drying began. We use moisture readings to determine when the equipment is no longer needed.

Can I use a household dehumidifier after water damage?

A household unit can help with everyday humidity, but it may not have enough capacity for wet structural materials or widespread water damage. Commercial equipment is designed to remove larger amounts of moisture.

Can dehumidification help prevent mold growth?

Removing excess moisture creates less favorable conditions for mold growth. However, existing mold, contaminated materials, or an unresolved moisture source may require separate remediation or repair.
