FAQs and Testimonials

At Alartco Windows & Doors, we aim to help people make informed choices about their doors and windows. That’s why we promptly answer all the questions we receive. Here, you can find answers to some of the frequently asked questions. Get in touch with us for more information about our products and services.

When should windows and doors be replaced?

Windows and doors should be replaced when:

  • You can feel cold drafts around the edges of the frames or along the joints or leaking between the sash, or it’s cold and uncomfortable being in front of the window or door
  • If you have single-pane aluminum windows
  • If they ice up in the winter
  • If any wood shows evidence of water damage
  • Dry rot
  • If you see gaps of light around the door

What are the benefits of replacing my windows and doors?

Replacing your old windows and doors can:

  • Eliminate cold drafts making your home warmer in the winter
  • Reduce heat gain in the summer, keeping your house cooler and more comfortable
  • Save you money on your utility bills by increasing your home’s energy efficiency and reduce your environmental impact and carbon footprint
  • Improve your home’s curb appeal, making your home look upgraded, well-maintained and welcoming
  • Increase the resale value of your home
  • Improve your home’s security

Who makes your windows and doors?

We manufacture and assemble our own line of windows and doors right here in Edmonton. Our window profile is supplied by Westech Building Products in Calgary, our door slabs are supplied by Novatech, also with a Calgary warehouse, our sealed units are supplied locally, and so are most of our parts and accessories. We aim to purchase our supplies locally in Edmonton and Alberta.

Do windows come in a standard size? Will custom made windows cost more?

No. There is not a “standard window size.” We custom make all our windows to fit each specific window opening. We do not expect you to re-do your siding, stucco, brick or re-drywall to accommodate a pre-made, “one-size-fits-all” window. Having your windows and doors made to order is very cost-effective.

Can I replace my windows and doors during winter?

Yes, absolutely! Winter is a great time to replace your windows and doors. When temperatures are low, we make sure we are quick and efficient, working on one window at a time, so your house is not open to the elements for more than a minute. Do be aware that for safety reasons and because we care about our installers, we may reschedule your installation if temperatures fall below -15°C.

What is Low-E?

Low-E (low-emissivity) is a coating applied to the surface of the glass that increases the energy efficiency and performance of a sealed unit. Low-E is an option offered on new windows that can dramatically improve the energy efficiency of your home. Simply put, Low-E helps keep the cold out and heat in during winter and keeps the heat out and coolness in during the summer. There are several Low-E coatings available, each offering a different level of performance and benefit. At Alartco, our standard coating exceeds the current energy rating standards.

What is a spacer and why is it important?

A spacer is a narrow strip of material, either foam, aluminum, or butyl, which separates the panes of glass from each other when making a sealed unit. Its purpose is to lower the thermal conductivity through the edges of the sealed unit and hence increasing the energy-efficiency of your window. At Alartco, we order our sealed units with Super Spacer®, a higher-performing insulating foam spacer. It substantially reduces condensation around the perimeter of the glass by providing a warmer temperature around the edge compared to other types of spacers.

What is argon and what does it do?

Argon is a clear, inert (non-reactive) gas that is denser than air sealed between the panes of glass in a sealed unit providing a measure of insulation.

Do I need a permit to change my windows and doors?

Depends. When replacing windows and doors, a permit is not required when replacing them for the same size. A permit is required if you are altering any part of the structure, such as making an opening larger or smaller.

Do I have to be a contractor to order from you?

No. You are welcome to place an order as supply only, but please double check your sizes and order details as we cannot be responsible for any errors made by others.

What do I do to prepare for installation?

Please arrange access to your home and any rooms involved in our work.

Please ensure that our crew can work safely and efficiently by arranging the following in advance:

  • Remove any blinds or curtains from the windows
  • Clear any items from doorways and pathways
  • Remove any furniture and electronics from in front of the windows
  • Remove any pictures and breakables from and around the adjoining walls

Alartco Windows & Doors Manufacturing Ltd. and their staff and associates are not responsible for any loss or damages that may occur during the installation process. The moving of furniture, removal of and re-hanging of blinds, curtains and shutters is the sole responsibility of the homeowner.

I changed my windows and doors and now I have condensation on my glass. Why?

The condensation you see on your glass and around your doors represents the amount of heat and energy (read $) that used to leak out of your house with your old system. Warm air holds moisture in the form of invisible water vapour and that water vapour will condense back into liquid when it contacts a cool surface such as glass or door hinges. This is a normal occurrence, but it can be troubling under certain circumstances. Be sure to manage the humidity in your home by adjusting your humidifier, running your bathroom and kitchen fans, or running your furnace fan.

Attention to Detail

We couldn’t be happier with the quality of the product and the attention to detail from Alartco and their installers. We had all the windows and front door done in the past year. The difference it made to the house was amazing. No more drafts and the house just feel so much more comfortable year-round. If I had to do it over again I would contact Alartco again without a second thought.

Professional, Knowledgeable, and Courteous

“We focus on standard work and prioritize customer satisfaction.
Here are some of the honest and useful reviews of our esteemed clients.

Alartco was the only company who showed up on time and ready to do business with us when we were trying to get quotes to replace all windows in our home (we had 2 other no shows and one other over 2 hours late). Professional, knowledgeable, courteous and quick. Loved every moment of dealing with Alartco and will happily contact them for any future businesses.
We love all our new windows.”

- Sheena Delisle

Fair and Honest Pricing

We were doing a complete home renovation and so we naturally went out to quote on windows from various vendors. After meeting with the various companies, I realized right away I was going to use Alartco.

Growing up in the construction industry for over 20 plus years in Calgary and now in Edmonton the one thing I have come to understand in the renovation world is nothing ever goes as planned! So, you better have great trades and suppliers on your side to deal with the inevitable changes.

Meeting with Tony at the house and talking through potential options, considering value for return on investment, installation challenges, impacts on other trades, etc. I was confident I found my new window supplier.

It was the local fabrication and smaller company feel that put me at ease. When a change happened, I did not need to wait six weeks to get a new window from another part of Canada or be put into a long manufacturing cue.

Fair and honest pricing, flexible installations, friendly advice and fantastic service … that is what you can expect from Alartco.

Second project now is also done with them. Recommending them to all my friends without hesitation.
