Our foundation repair services in Ottawa help homeowners address cracks, settling, bowing walls, water infiltration, and other structural foundation issues. Our experienced team assesses the condition of your foundation and provides reliable repair and stabilization solutions designed to protect your home and prevent further damage.
Your foundation carries the entire house, so cracks, leaks or movement should be looked at early. Aelia Construction and Design repairs residential foundations across Ottawa, focusing on lasting fixes rather than quick patches.
Ottawa homes deal with freeze and thaw cycles, heavy spring runoff and, in many areas, clay soils that move. These conditions can cause cracking, leaks and settling over time. We assess the cause of the problem first, because repairing a symptom without fixing the cause rarely lasts.

Every home and project is different, so we price each job after seeing it. These are the main things that shape your estimate:

- Access to the foundation, inside and outside
- Depth and length of excavation needed
- Whether an engineer’s design is required
- Drainage and landscaping that must be removed and restored
- Waterproofing method selected
Frequently asked questions
Are all foundation cracks serious?
No. Hairline shrinkage cracks are common. Cracks that are wide, growing, horizontal, or leaking deserve an inspection. If in doubt, have it checked.
What are signs of a foundation problem?
Stair-step cracks in brick, doors and windows that stick, sloping floors, gaps between walls and ceilings, bowing basement walls, and water or damp patches in the basement.
Do I need an engineer?
For structural movement or bowing walls, an engineer’s assessment is usually recommended. We can coordinate this and carry out the repair they specify.
Can repairs be done in winter?
Some interior repairs can. Exterior excavation is easier and more reliable in warmer months. We advise on timing during the inspection.
