Siding Installation in Shawnigan Lake and the Cowichan Valley
Siding installation and repair in Shawnigan Lake, Mill Bay, Cobble Hill, Duncan and Ladysmith
Your siding keeps the rain out, and on Vancouver Island it works hard for it. Matts Island Construction installs, repairs and replaces siding across the Cowichan Valley, along with the soffits, fascia and trim that finish it.
Whether you need a damaged section replaced, new siding on part of the house or a whole wall redone, we find what's letting water in and fix it properly.
What we do
Siding: installation, repair and replacement in fibre cement, vinyl, wood and metal. Soffits, fascia and trim: replaced or added to match, with vents and downspouts sorted while we're up there.
Signs it's time to call: siding that's cracked, warped or bulging, paint that won't stay on, gaps at the trim, or soft spots and stains on the wall.
Inspect first
We look at the wall from outside and in, to find where water is getting through.
Honest estimate
You get a clear quote for what needs fixing, not a pitch for more than you need.
Repair properly
Damaged boards, flashing and trim are replaced and sealed so the fix lasts.
Match the house
New siding, soffits and trim are matched to what you have, so the repair disappears.

Keep the rain out
Small leaks don't stay small. Water behind siding leads to rot, mould and damage inside the walls, often long before you see it. A timely repair costs far less than fixing what water leaves behind.
Adding on? We match new siding and trim on additions and garages too.

What our customers say
Matt was hired to remove the old siding from our dormer and replace it with new hardiplank siding. He also installed soffits, a vent cover, and extended the top downspout to the lower gutter. ... He completed the work quickly and to a high standard.
Smily Matt was all biz, showed discipline, courteous behaviour and most of all a flawless finish to a job well done.
Very honest,reliable and knowledgeable
Siding questions
Can you repair just part of my siding?
Often, yes. If matching material is available, we can replace damaged boards or sections without redoing the whole wall. If it can't be matched, we'll talk through your options.
Which siding material is best?
Fibre cement is durable and fire resistant, vinyl is the most affordable and needs little upkeep, and wood gives a classic look but needs regular painting or staining. We'll help you weigh cost, looks and upkeep for your home.
Can you match the siding on an addition or garage?
Yes. On additions and garages we match the siding, soffits and trim to the house wherever possible, so the new part looks like it was always there.
Do you do roofing?
We don't take on general roofing. By special request we apply vinyl membrane to deck roofs and flat porch roofs over living space, the same system we use on vinyl decks.
Do you work in my area?
We install and repair siding from Langford and the Malahat up to Ladysmith and Nanaimo, including Shawnigan Lake, Mill Bay, Cobble Hill and Duncan.
