Whitby Foundation Repair

A leaking crack, damp basement wall or visible foundation movement can be difficult to diagnose without looking at the entire problem.

Aquaphobia Foundation Repair provides professional Whitby foundation repair services for homeowners dealing with foundation cracks, basement water, block-wall moisture, bowing walls and other foundation concerns.

Call 289-212-9326 or send us photos of the affected area to get started.

Foundation Repair Services in Whitby

The correct foundation repair depends on the type of foundation, condition of the wall, source of the water and whether structural movement is present.

Aquaphobia provides several foundation and basement repair services throughout Whitby.

Foundation Crack Repair

Poured-concrete foundation walls can develop vertical and other cracks over time.

A crack may initially appear harmless but later allow water into the basement during periods of heavy rain or saturated soil conditions.

For suitable cracks, polyurethane injection can often repair the water pathway from inside the basement.

If you’re specifically dealing with a foundation crack, visit our Whitby Foundation Crack Repair page for more information.

Basement Waterproofing and Wet Basement Repair

Basement water problems are not all caused by the same thing.

Possible entry points include:

Foundation cracks
Block foundation walls
Window wells
Wall penetrations
Wall-floor joints
Exterior drainage conditions
Other weaknesses in the foundation

Before choosing a basement waterproofing method, the source of the water should be identified.

Some problems can be repaired from inside, while other conditions may require exterior waterproofing or drainage work.

Concrete Block Foundation Repair

Moisture in a block foundation may appear across a larger section of wall instead of through one obvious crack.

Signs can include:

Damp blocks
White deposits
Peeling paint
Dark staining
Moisture near the floor
Musty smells
Water following prolonged rainfall

Certain block-wall conditions may be suitable for interior cementitious waterproofing treatments.

The wall needs to be properly prepared so the treatment can bond to the masonry.

Our information about block foundation waterproofing explains these types of problems in more detail.

Bowing Foundation Wall Repair

A foundation wall that is visibly bowing inward should be evaluated differently from an isolated leaking crack.

Horizontal cracking can sometimes accompany wall movement.

Depending on the condition and amount of movement, carbon fibre foundation reinforcement may be appropriate for certain walls.

More significant structural concerns may require evaluation by an appropriate structural professional.

Basement Floor Crack Repair

Basement floor cracks are relatively common, but their condition can vary.

Some remain stable and dry, while others may experience water entry, deterioration or displacement.

The appropriate basement floor crack repair depends on what is happening with the concrete and surrounding area.

Foundation Parging Repair

Parging covers the exposed exterior surface of many foundations.

Over time, weather and moisture can contribute to cracking, flaking or deterioration.

Aquaphobia provides foundation parging repair for suitable foundation surfaces.

The underlying area should be inspected before new material is applied so damaged or loose material can be properly addressed.

Common Foundation Problems in Ajax Homes

Foundation and basement problems can become more noticeable during periods of heavy rain, snowmelt and changing seasonal conditions.

Problems homeowners may notice include:

Leaking vertical cracks
Horizontal foundation cracks
Damp basement walls
Water after storms
Bowing walls
Concrete block moisture
White mineral deposits
Failed previous repairs
Floor cracks
Deteriorating parging

The appearance of one of these conditions does not automatically mean the foundation has serious structural damage.

The pattern of the problem, presence of water and any visible movement are important when determining what repair may be appropriate.

Structural vs Non-Structural Foundation Problems

A foundation crack and a structural foundation problem are not necessarily the same thing.

For example, a stable vertical crack may primarily create a pathway for water.

A horizontal crack accompanied by inward wall movement may require a different approach.

Aquaphobia evaluates the type of problem before recommending a repair.

If a condition appears to require engineering or structural assessment, an appropriate structural professional may be required.

Interior vs Exterior Foundation Repair

Many homeowners associate foundation repair with excavation.

Exterior foundation work is sometimes necessary, but it is not the only option.

Many suitable poured-concrete cracks can be repaired from the interior.

Interior approaches can sometimes avoid disturbing exterior features such as:

Landscaping
Walkways
Decks
Patios
Driveways
Air-conditioning equipment

Certain block-wall moisture problems may also have interior treatment options.

The repair should be selected based on the actual source and condition of the problem.

 Trustindex verifies that the original source of the review is Google. It was the best of times,it was the worst of times.   A leak found in our foundation on the day of our open house.  We chose full disclosure to all prospective buyers.  I called up John at Aquaphobia.  John asked a few poinent questions and reassured me that solutions were available.   I sent a picture, and with a phone call, John provided a detailed description of the problem and the solution.  John arrived at the agreed upon time later that day.  Then proceeded to do exactly what he said he would do.  He saved the day.  With a warranty to stand behind his work we were able to redo the paperwork for the sale of the house and proceed.  All at a fair price.  A written receipt described the treatment and my real-estate agent was satisfied that we had done our due diligence.  Highly recommend.

 Trustindex verifies that the original source of the review is Google. Jon was a tremendous help as we navigated a home inspection that required a foundation expert in very short notice. Jon rearranged his schedule to accommodate an evaluation/inspection the very next day after we spoke. His knowledge and experience was very helpful and gave us the piece of mind to purchase the property. Thanks again Jon!

 Trustindex verifies that the original source of the review is Google. Jon was guick to respond to my initial inquiry and gave good communication throughout. He also came out in a very acceptable timeframe to do the basement repair. The repair was done in the time window Jon provided and the work was completed to our satisfaction. Jon inspected the outside wall to ensure the crack was fully filled and he cleaned up also and left the basement area tidy. Would highly recommend.

 Trustindex verifies that the original source of the review is Google. I called aquaphobia on thanksgiving weekend after finding water in my furnace room. Honestly I wasn’t even expecting someone to answer the phone given that it was thanksgiving weekend, and I just planned on leaving a msg hoping they would get back to me. Nope, answered the phone and were happy to help. They got me to send them some pics of the situation and we went on from there. Super helpful, knowledgeable, patient, and friendly. 10/10 would recommend especially to new home owners
