How do I know if I have enough attic insulation in Cornerstone?

Measure the depth at a few points across the Cornerstone attic rather than one. If it sits level with or below the ceiling joists in a Cornerstone attic, or varies a lot across the space, there is usually room to improve it. We measure it properly on the Cornerstone visit and tell you either way.

Can you add insulation on top of what is already in my Cornerstone attic?

Usually yes -- if what is in the Cornerstone attic is dry and in reasonable condition, adding depth on top is the normal approach and the cheaper one. If what is in your Cornerstone attic is wet, damaged or unidentified, that gets dealt with first.

Will topping up my attic help with ice dams in Cornerstone?

It is usually where the problem begins, because ice dams generally come from heat escaping into a Cornerstone attic and warming the roof unevenly. Insulation and air sealing are the normal first step in a Cornerstone home, but anyone promising a guaranteed outcome without looking at the roof is guessing.

What if there is old wiring in my Cornerstone attic?

If we find wiring of a type that should not be buried in insulation in your Cornerstone attic, we stop and it goes to an electrician first. It is a genuine fire consideration in a Cornerstone home and it is not something we assess ourselves.

What if there is a grey chunky material in my Cornerstone attic?

Any material we cannot confidently identify in a Cornerstone attic is treated as unknown until it has been tested. We stop, tell you, and do not disturb it or cover it over in your Cornerstone attic. Testing is arranged through a qualified lab, not carried out by us, for any Cornerstone property. We also cover Homestead, Moraine, Twinhills and every Calgary quadrant.

Attic insulation in Cornerstone, brought up to an even depth

The attic is the easiest part of a Cornerstone house to under-insulate and the easiest to ignore, because nobody looks at it. Most of what we find in Cornerstone is not missing insulation — it is insulation that has settled, been walked on, been pushed aside by someone working up there, or simply never went deep enough. Cornerstone is an NE Calgary community with a mix of older homes and newer builds, so insulation calls here range from basement development in the newer homes to attic and wall upgrades in the older ones nearby. We cover Cornerstone, Homestead, Moraine, Twinhills and every Calgary quadrant, 7 days a week.

What affects the cost of attic insulation in Cornerstone?

Area, depth and access

Attic insulation cost in Cornerstone depends on the square footage of the attic, how much depth is being added, and how easy the attic is to get into and move around in. A low-pitch Cornerstone attic with a small hatch takes longer than a tall one with good access.

What can change it

Removing existing material, or anything found up there that has to be dealt with first, is priced separately -- and you are told before the work rather than partway through it. Much of Cornerstone carries an orange-peel finish, which is easy to apply and unforgiving to match badly.

How to tell what you already have in a Cornerstone attic

Depth is the honest measure

The only dependable way to know in a Cornerstone attic is to measure the depth in several places, because it is rarely even. If it is level with or below the ceiling joists, there is usually room to improve it.

Why it is uneven

In most Cornerstone attics the insulation near the hatch and along traffic routes is thinner — compressed by anyone who has been up there for wiring, plumbing or a bathroom fan. The middle can look fine while the edges are bare.

What we do on the visit

In your Cornerstone attic we measure in several spots, look at the eaves, the hatch and the ductwork, and tell you what is actually there before quoting anything.

Common attic insulation situations in Cornerstone

In Cornerstone, cornerstone is a community built out in the 2000s. Homes of that vintage generally have knockdown ceilings and orange-peel walls, and the common calls are settling cracks, nail pops and basement development. Same trusted team, same process on every job — on-site quote, fixed price, no surprises.

When a Cornerstone attic is not a simple top-up

Material we cannot identify

Some older Cornerstone attics hold a grey-brown pebbly material rather than batt or blown insulation. We treat it as unknown until it has been tested -- in your Cornerstone attic we stop, we tell you, and nothing is disturbed or covered until you know what it is. We do not identify it and we do not remove it from a Cornerstone attic.

Old wiring

If old wiring of a type that should not be buried turns up, it goes to an electrician before anything is covered over. That is not a judgement we make ourselves on a Cornerstone job.

Frost, damp or damaged insulation

Insulation that is wet or frosted is a sign of something else going on, usually air leaking up from the house. Adding depth over the top hides the problem rather than fixing it, so in a Cornerstone attic we report what we find and why instead of blowing over it.

Ice dams

Ice dams are usually driven by heat escaping into the attic. Insulation and air sealing are the usual place to start in a Cornerstone attic, but nobody can promise you a result on a roof they have not looked at. Much of Cornerstone carries an orange-peel finish, which is easy to apply and unforgiving to match badly.

Why Cornerstone homeowners have us handle the attic

You get told what is actually up there

The attic is the easiest place in a Cornerstone house to be told a story about, because almost nobody climbs up to check. We measure it, and if what we find changes the job in your Cornerstone home, you hear it before the work rather than after.

One contractor for the whole envelope

We handle the attic, the insulation below it and the drywall that closes it in — one company answerable for the result rather than three trades pointing at each other.

Fixed price, same-day reply

We cover Cornerstone and every Calgary quadrant, 7 days a week. Free on-site quotes in Cornerstone and a fixed price before any work starts. Basement development is common in Cornerstone, and a basement behaves differently from the rest of the house — cooler, damper, and less forgiving of a rushed finish.

Cornerstone: what shapes the job

Housing in Cornerstone is mixed enough that two jobs on the same street can need completely different attic insulation work.

A lot of the work in Cornerstone starts in the basement, where the ceiling has to stay openable for the plumbing and ducting above it.

Orange peel is common on Cornerstone walls. It is quick to apply and unforgiving to match, so the tip and the timing matter more than the mud.
