Real customers. Real Results. Unscripted.

As a new home owner I was very careful finding a contractor who I could trust. I was looking for a company I could count on for whatever came up. They met all my expectations!
I hired Alexander to install two exterior doors on my house and 1 exterior door on my garage.
Work was done with the up most quailty and care for my property.

I had an exterior window/door project with a tight deadline and Brian and his crew came through for me! I appreciated and was impressed at the responsive and timely communication throughout the project and the quality of the work performed. I would confidently recommend and/or use Alexander Exteriors again!

Alexander Exteriors is top notch. From start to finish the company and its employees were great to work with, I will continue to use Alexander Exteriors and will recommend them to all my clients, friends, and family. The windows look great. The customer service was unbeatable. You will not be disappointed using Alexander Exteriors.

I have used this company twice in the last year to install new windows in my living room and kitchen. The owner is such an excellent person to work with. They were polite, fast, professional. My vision was brought to life. There were no complications with the instal. Their techs were top notch. I plan on doing some home renovations and without doubt will be using these guys again. I give them a 10/10.

Amazing experience! I was super frustrated… We had been looking to find a solution for replacing our old single pane windows for nice new windows. It was a headache. We called Jasen at Alexander Exteriors and within minutes he had answered the questions we had spent days looking for information about. Knowledgeable, friendly, and so helpful! I will never need to look anywhere else for exterior renovations on my house! Alexander Exteriors is dedicated to taking care of their customers and getting the job done right! They’ve won my trust!

I couldn't be happier with the windows installed by Alexander Exteriors! Our original windows from 1975 were inefficient and falling apart. We chose to work with Alexander because they were incredibly responsive, fair, and honest—he took the time to consider both my and my husband's opinions, which I truly appreciated. They went above and beyond to make sure our experience was nothing less than stellar. And his team? Absolutely top-notch professionals! They consistently communicated, showed up on time, and even braved sub-zero temperatures and harsh winds to get the job done—though I would have completely understood if they stayed home! The great sense of humor also made the entire process enjoyable; he always managed to keep things light and fun, even during the more stressful moments. Despite the work being extensive, I experienced minimal disruption while working from home. Alexander Exteriors has exceeded my expectations, and I would highly recommend them to anyone in need of new windows.

Frequently Asked Questions

With clear, direct answers to most homeowners window and door questions:

How much does a typical window replacement project cost in the Twin Cities?

Most of the window replacement projects we do in the Twin Cities fall between $15k–$40k.

Smaller jobs — like replacing 3–5 standard vinyl windows — usually start around $5k–$10k.
Larger projects — full-home replacements, custom sizes, or premium materials — can be $50k+.

After a quick call and a few photos, we’ll give you a clear ballpark range before anyone comes to your home, so you can see if it fits your budget with zero pressure.

What's the difference between wood and vinyl?

In simple terms: wood looks better upfront, vinyl costs less over time.

Wood windows (pine, oak, or clad wood): higher initial price, need painting or sealing every 10-15 years, can swell, rot, or peel if neglected, typically last 20-25 years with good care.


Vinyl windows: lower upfront cost, no painting or sealing, resist rot and moisture, very energy-efficient, and can last 25+ years with basic cleaning.


During your consultation, we’ll show you good / better / best options in both materials so you can see side-by-side how the look, maintenance, and price compare.

What does the process look like from first call to finished windows?

Our job is to make this simple:

  1. Phone / virtual consult to talk through your ideas, budget, and timeline.
  2. On‑site visit & measurements so we can design to your exact space.
  3. Design & proposal with a clear scope, price, and options.
  4. Permits & HOA approvals handled by our team.
  5. Install phase where our crew completes the project and keeps your home tidy.
  6. Final walkthrough to make sure everything looks and functions exactly how you expected.

Most projects move from first call to completed in about 6-8 weeks, depending on design and permits.

How long does it take to get permits and start install?

In most cities, permits typically take about 2-3 weeks once plans are submitted. Some projects are faster, more complex designs can take a bit longer.

On the other hand, most windows and doors are custom ordered and take 4-6 weeks to arrive.

We handle all drawings, paperwork, and back‑and‑forth with the city/HOA for you, and we keep you updated so you’re never wondering where things stand. Once permits are approved, we schedule your start date and lock it in.

Are you licensed, insured, and familiar with local building codes?

Yes. Alexander Exteriors is a fully licensed and insured contractor in the state of Minnesota.

License: #BC723426

Coverage: 7-Figure Liability Coverage

We pull all required permits, install to code specifications, and coordinate inspections so your install is safe, legal, and ready to enjoy.

Do you offer financing or payment plans?

Yes. For qualified homeowners, we offer financing through our trusted partners so you can pay for your deck over time instead of in one lump sum.

Options often include:

  • Terms from 12–120 months
  • Payments as low as $250/month on typical projects
  • Fast approvals, with no obligation to move forward if the numbers don’t feel right

Ask us during your consult and we’ll walk you through the options for your exact project amount.

What kind of warranty do you offer on workmanship and materials?

You get 1-year workmanship coverage from Alexander Exteriors. If something we installed fails due to our installation during that time, we fix it at no labor cost to you.

On top of that, many of the windows and doors we use carry manufacturer warranties of 20–50 years.

What happens if something goes wrong or I'm not happy after the project?

If something isn’t right, we make it right.

Here’s how we handle it:

  1. You let us know what’s wrong.
  2. We schedule a visit to inspect and diagnose the issue.
  3. If it’s related to our workmanship within 1 year, we repair it at no labor cost.
  4. If it’s a material issue, we help you work directly with the manufacturer to use your product warranty.
What happens after I fill out the form?

You’ll hear from us within 60 minutes during business hours (or first thing the next business day).

  1. We’ll confirm a few details about your project and answer initial questions.
  2. We’ll ask for photos of your existing windows so we can come prepared.
  3. We’ll schedule a phone or in‑home consultation at a time that works for you.

No spam, no endless sales calls – just a clear plan, a price range, and next steps so you can decide if we’re the right fit.
