Attic Insulation & Ventilation
The largest single opportunity in most Toronto houses, and the one most often done in the wrong order. Inspection, air sealing, ventilation protection, then an even top-up.

Services
You do not need to know which service you need.
That is our job. Start from the symptom, and the correct scope tends to reveal itself once somebody has actually looked.
Choose by symptom
What does your house do that bothers you?
Each path below leads to the service most likely to be relevant. None of them is a diagnosis, and several symptoms legitimately point in more than one direction.

One system
Three services that are really one job.
A house does not have an attic problem and a separate basement problem. It has a pressure difference between inside and outside, and a set of openings that pressure difference is using.
Air Sealing & Draft Control
Investigation of the paths air is actually taking, then targeted work at the ones worth closing. Distinct from insulation, and distinct from an official energy evaluation.
Full scope, tools and FAQ →Basement & Rim-Joist Insulation
The bottom of the house, where cold floors and basement-edge drafts usually begin. Moisture is settled before anything thermal is installed.
Full scope, constraints and FAQ →How they combine
Most projects are not one service.
Here is how the three fit together in practice, and what a combined scope usually looks like.
Attic plus air sealing
The most common combination, because the sealing work happens in the same space and under the same access. Doing them separately means paying twice for setup and moving insulation twice.
Attic plus basement
Sometimes the right answer when the house has a strong stack effect: air leaves at the top and enters at the bottom. Treating only one end can shift where you feel the draft without reducing it much.
Pre-renovation envelope planning
If walls or ceilings are about to be opened, that is the cheapest air sealing you will ever buy. We will happily do a review that results in a very small invoice and a good sequence for your other trades.
Moisture-first assessment
When dampness is part of the picture, the envelope work waits. Sometimes the correct outcome of a Latchline visit is a referral and a phone call in three months.
What we do not do
A short and deliberate list.
- We are not energy advisors and we do not conduct official EnerGuide evaluations. Where one is needed, we will tell you and point you to the right people.
- We do not determine rebate eligibility. Programs, amounts and requirements change, and the decision is not ours to make.
- We do not remove vermiculite, asbestos-containing materials or mould-like growth. We stop and refer.
- We do not do roofing, plumbing, electrical or waterproofing work. We frequently coordinate with the people who do.
- We do not spray foam an assembly simply because spray foam exists. Material follows access, moisture and construction, not the other way round.
Not sure which of the three you need?
The Scope Planner will point at a starting area based on what you have observed, and tell you plainly when the answer is that nobody can know yet.
