Diagnose the Problem

Signs Your Siding May Need Attention

What you see on the surface isn’t always the actual problem. Here’s what to look for.

Cracking, warping or buckling

Your siding may be deteriorating, improperly installed, or allowing moisture behind the exterior.

Soft or spongy spots

Can indicate the sheathing or framing behind the siding has started to deteriorate.

Peeling or bubbling paint

Persistent moisture can cause exterior coatings to fail prematurely, often a sign it’s trying to escape from inside the wall.

Not every problem means you need new siding. Some issues can be repaired. Others point to problems behind the cladding that need investigating, so see “Do You Need to Replace All Your Siding?” below. Not sure what you’re looking at? Send us a few photos or request an on-site assessment.

Making the Call

Do You Need to Replace All Your Siding?

Not necessarily. Here’s how we think about it.

Repair may make sense when:

Damage is localized, most siding is in good condition, a matching material is available, and the wall assembly underneath is sound.

Replacement may make more sense when:

Damage is widespread, moisture has reached the wall assembly, the siding is near the end of its life, or you want to change the material or look.

How Your Exterior Actually Works

Your Siding Is Only the Outer Layer

Siding protects your home from the elements, but it isn’t the only thing keeping water out. Behind the cladding is a system of weather barriers, drainage, flashing and structural materials that all work together to protect the wall.

The rainscreen cavity sheds most of the rain that hits your home and lets any that gets through drain and dry out.

The weather-resistant barrier is the backup layer if water gets past the siding and cavity.

Sheathing and framing are structural. They’re not designed to handle ongoing moisture exposure.

A failure in any one layer can go unseen for months before it shows up as a visible problem.

What Happens When Water Gets Behind the Siding?

Stage 1

Water enters

Failed flashing, gaps or damaged materials can allow moisture behind the cladding.

Stage 2

Moisture gets trapped

Without proper drainage and ventilation, moisture can remain against the wall assembly.

Stage 3

Damage develops

Over time, persistent moisture can contribute to rot, mould and deterioration.

This is why the installation behind the siding matters just as much as the siding itself, and why every Tomron siding replacement includes a full inspection of what’s underneath.

No Surprises

What If We Find Damage Behind Your Siding?

Removing siding sometimes reveals moisture damage or deterioration we couldn’t see from outside. If that happens, we stop, show you what we found, and agree on next steps before any additional work or cost.

The Details That Matter

Siding Isn't What Keeps Your House Dry

Water management comes down to the details around the openings and transitions in your walls, the places every exterior system is most likely to fail.

Windows

A common source of hidden water intrusion when the flashing around them isn’t detailed correctly.

Doors

Need the same careful flashing and sealing as windows, especially at thresholds.

Roof-to-wall

Where two exterior systems meet, a frequent cause of interior leaks when poorly detailed.

Decks & penetrations

Each needs its own flashing detail; easy to miss and a common failure point.

Tomron’s combination of siding, metal flashing and building envelope experience means we understand what happens behind the exterior, not just on it.

Budgeting

What Does Siding Replacement Cost?

Your project cost depends on a handful of factors:

Home size & storeys

Material chosen

Windows, doors & corners

Envelope condition

Flashing & rainscreen

Removal & disposal

Site access

Project scope

Common Questions

Questions Homeowners Ask

Straight answers from the crew who do the work. If yours isn’t here, send us a message and we’ll get back to you.

Can you repair my siding instead of replacing it?

Sometimes. If damage is localized and a matching material is available, a repair can be a lasting fix rather than a full replacement. We’ll tell you honestly which makes sense during your assessment.

Does siding replacement include work on my building envelope?

It can. Once your existing siding is off, we inspect the sheathing and moisture barrier underneath and quote any envelope repairs needed before new siding goes on.

What happens if you find rot or moisture damage behind my siding?

We stop, show you what we found, and agree on next steps before any additional work or cost.

Do I need a rainscreen?

BC Building Code requires one on most residential exterior walls, and we install it as standard on our siding replacements. Vinyl is the exception: when it is installed horizontally, its hollow-backed profile and loose fastening already create a built-in drainage and drying gap, so it does not need a separate rainscreen. It still goes over a proper weather barrier. Fibre cement, wood and metal panels do need one.

Which siding material is best for a Lower Mainland home?

Fiber cement holds up extremely well to our rain; vinyl is a strong budget option; wood and composite suit homes where a specific look matters. We’ll help you weigh it against your home and budget.

How long does a siding installation take?

Most residential projects take 1 to 3 weeks depending on size and complexity. You’ll get a firm estimate after your free consultation.
