Dowling General Construction

Dowling General Construction is a general contracting business based at 6860 Lambeth Walk in London, Ontario, reachable at 519-657-5311 or through its website. The company works on the structural side of home ownership — the parts of a house that homeowners rarely think about until something goes wrong: the foundation underneath, the basement below grade, the roof overhead, and the brick and masonry that hold everything together. For a lot of homeowners, construction terminology can feel like a foreign language. This page walks through what Dowling General Construction actually does, in plain English, so anyone calling in for the first time knows what to expect and what questions to ask.

Each of those eras of construction comes with its own weak points — older mortar joints that have simply worn out over decades, basements that were never properly damp-proofed to modern standards, or foundations poured before today's drainage practices were common. A local contractor working across these different building types day to day develops a practical sense of what tends to fail first in this particular city, and that is the value of calling someone based in London rather than a crew driving in from out of town.

Foundation repair, in plain language

Foundation repair means stopping and correcting movement, cracking or deterioration in the concrete or block structure that a house sits on, so that everything built above it stays level and secure. The words used around this kind of work can sound alarming — "settling," "heaving," "shifting" — but they describe a fairly specific set of problems that a trained eye can usually diagnose by looking at the pattern of a crack.

What "settling" and "heaving" actually mean

Settling is when soil under part of a foundation compresses or washes away, so that section of the house sinks slightly lower than the rest — it often shows up as a diagonal crack running from a corner of a window or door. Heaving is the opposite: soil (often clay-heavy, which is common in this region) expands when it absorbs water or freezes, pushing up on a foundation wall or slab from underneath. London's freeze-thaw cycle, where ground temperatures swing above and below zero repeatedly through the winter and into spring, is exactly the kind of condition that triggers both problems over time.

Why a hairline crack is not automatically an emergency

Not every crack in a foundation wall means the structure is failing. A crack that is wide, growing, or paired with a door or window that has started sticking is a different situation and worth having assessed sooner rather than later, because the longer that kind of movement continues, the more it can affect the rest of the structure sitting on top of it.

Wet basements and moisture control

A wet basement is any lower level of a home where water is getting in from outside, either as visible seepage or as trapped humidity that shows up as a musty smell, mold, or damp walls. Waterproofing work addresses where that water is coming from and redirects or blocks it, rather than just covering the symptoms.

The difference between "damp-proofing" and "waterproofing"

These two terms get used interchangeably, but they are not the same thing. Damp-proofing is a lighter coating applied to a foundation wall mainly to resist moisture absorbed directly through the concrete. Waterproofing is a more complete system meant to actively keep pressurized groundwater out, which typically matters more for homes with a history of active leaks rather than general dampness. Knowing which one a basement actually needs is part of what a proper assessment sorts out before any work starts.

Why basements in this area act up most in spring

London basements tend to show water problems most in early spring, when snowmelt combines with spring rain faster than already-saturated ground can absorb it, pushing water against foundation walls from the outside. Grading around the house, downspout placement, and the condition of a home's weeping tile (the perforated pipe running along the base of the foundation that is meant to carry groundwater away) all affect how a basement handles that seasonal surge. Odour, visible mold, or a damp feeling in a basement are all worth investigating even if there is no standing water in sight, since moisture can be entering slowly through the concrete itself rather than through an obvious leak.

Roof, brick and masonry work

Beyond foundations and basements, this kind of general contracting work also covers roof repair and masonry — the brick, mortar and chimney work that makes up the visible shell of a house. Both areas deal with materials that are constantly exposed to the weather and wear down gradually rather than failing all at once.

What "repointing" means for older brick homes

Repointing is the process of removing old, crumbling mortar from between bricks and replacing it with fresh mortar, without disturbing the bricks themselves. It is common maintenance for older brick homes, since mortar is a softer material than brick by design — it is meant to wear out first and be replaced, rather than let the bricks themselves crack under stress. Homes in London's older neighbourhoods, where brick construction from decades past is still standing, are the ones most likely to need this kind of work eventually.

Flashing, and why it matters more than the shingles

Flashing is the thin metal installed around roof edges, chimneys and valleys to direct water away from the seams where a roof surface meets another part of the house. A surprising number of roof leaks trace back to failed or poorly installed flashing rather than worn shingles, because that is where water finds the easiest path in. On a chimney specifically, flashing failure and deteriorating mortar around the chimney stack often go hand in hand, which is why roof and masonry problems frequently get diagnosed together rather than separately.

Frequently asked questions

Does Dowling General Construction only do foundation and basement work?

No. While foundation repair and basement waterproofing are core services, the business also handles roof repair, brick and masonry work including chimneys, and general construction projects beyond what is listed on its website — homeowners with a project that does not fit neatly into one category are encouraged to describe what they need and ask directly.

How do I know if my crack needs a professional look?

A wide, actively growing crack, or one appearing alongside doors and windows that no longer close properly, is worth having assessed. A thin, stable hairline crack in poured concrete is usually lower priority but still worth sealing to keep moisture out over time.

Why does my basement only get damp in certain seasons?

Basement moisture in this region is closely tied to spring snowmelt and heavy rain overwhelming the ground's drainage capacity around a foundation. A basement that is dry most of the year but damp for a few weeks in spring is often reacting to that seasonal groundwater pressure rather than a constant leak.
