Straight answers, including the awkward ones.

It depends on opening size, style, glazing, install type, access and finish, and those vary enough between houses that a published range would be wrong for most people who read it. Call us or book a free estimate and we will measure and give you a real number in writing.

Yes. We measure, we quote in writing, and there is no charge and no obligation whether you go ahead or not.

Because a figure on a web page is a guess about your house, and we would rather measure than have you plan around a number we invented. What we do publish is the exclusions — what a quote does not cover — which is the part that actually causes the surprises.

Rot or structural repair found once the old unit is out, interior finishing beyond the opening, permits where an opening is enlarged, and disposal beyond the units we remove. Your written quote lists the specific ones that apply.

For most Edmonton homes, yes — it runs −25 to −35 °C for weeks at a time, and triple-pane is also what CEIP financing requires here. We fit both, so it is your call: on a sheltered elevation or a tighter budget, double-pane is a sound choice and we will say so.

A U-factor no higher than 0.21 and an Energy Rating of at least 34. Canada dropped its regional climate zones in January 2020, so one national standard now applies coast to coast.

Up to 25% of a home’s total heat loss. In a heating-dominated climate that converts directly into utility cost, which is why the envelope matters more here than in milder provinces.

No. In this climate they need refinishing on a schedule most people do not keep, and we would rather decline than sell you something that looks poor in four years.

Yes, down to about −20 °C. We use cold-weather foams and sealants, work one opening at a time, contain the work to a single room, and leave old units in place overnight on multi-day jobs. Vinyl does get more brittle in deep cold, which slows cutting.

Usually. Demand is lower between December and February, so scheduling is more flexible and lead times are shorter.

One to three days for most homes. Product lead time before that varies by manufacturer and season, and we give you the current figure at quote stage.

No. We work one opening at a time and close the house up every night, including on multi-day jobs.

Not for a like-for-like replacement in an existing opening. You do need a City of Edmonton building permit if the opening is being enlarged or the foundation cut.

At least 0.35 m² of clear opening with no dimension under 380 mm, openable from inside without tools and able to stay open unsupported. This is the National Building Code (Alberta Edition) requirement for egress.

Yes. Window changes facing a side property line require elevation drawings and may require a development permit as well. It is a planning requirement rather than a building one, so it catches people out late.

No. The grant closed to new applications in February 2024 and the loan closed in October 2025. Any company still advertising them is advertising something you cannot join.

The Clean Energy Improvement Program, which is City of Edmonton financing repaid through your property tax bill at 6.00% fixed for up to 20 years, and dealer financing through us. CEIP is currently nearing capacity with new pre-qualifications waitlisted.

Yes. The balance and the improvement both pass to the new owner, because the financing is attached to the property rather than to you.

Yes. Most companies in this trade will not, which is why people end up replacing a window that needed a small part.

No, never. We do not cold-call either. If someone claiming to be from Helovs turns up uninvited, they are not from Helovs.

Yes. Alberta law gives you 10 days to cancel a prepaid contract after you receive your copy, for any reason and with no penalty. We print that on the quote.

No. We are a dealer, and we install product from two manufacturers. That means we can tell you when a cheaper line is the right answer for a given opening.
