OPERATING HOURSMonday – Sunday: 8:00 AM – 9:00 PM

Basement Builders is solely focused on basement renovations and is an expert in underground structures. Since 2012, this contractor has provided attention to detail to just about any type of basement project.

This contractor follows a step-by-step procedure, from the start-up process to the build. The start-up process begins with a quick initial estimate, finalization of the estimate, final review, and selection.

The build phase then consists of the pre-construction stage where they’ll help with set-up and even acquisition of permits. Then, Basement Builders proceeds with the construction, final furnishings, and even city inspections.

All throughout the process, Basement Builders guarantees to provide smooth communications. Although, we’ve heard some reviews about some staff dictating terms to clients.

But since it follows a high standard for quality and makes sure all aspects are first approved by clients, construction may take 7-9 weeks and its base prices are at $29,000.

Nonetheless, we commend this contractor as it’s Baumler-approved, meaning that it has a great track record of exercising accountability for all its projects.

Moreover, Basement Builders offers financing options lasting up to 15 years, all thanks to its partnership with FinanceIt. This contractor also holds a $2 million insurance liability.

Lastly, we find it appealing that Basement Builders offers a 5-year warranty for both materials and labour. 


  • 5-year materials and labour warranty
  • Financing options available
  • Baumler-approved
  • Quick online estimates available
  • Helps with inspections and permit acquisition
  • All week availability


  • Long turnover time
  • Some complaints about pushy attitude on terms
  • No on-site visits

Customer Reviews

High quality work, professional contractors

“We had them renovate most of an 1,100 sq foot basement in about 9-10 weeks, with short notice. They did an office/bedroom, den/family room, bathroom, and closed off a storage room and the utility room. Everything looks great, very high quality work, and the subcontractors they use were all very professional. They’ve clearly done this many times: they have a well thought out process/contract/agreement form, they post signs at the door and lay down floor protector, arranged for us to pick lights, cabinets, paint, flooring, tile, etc at a minimum places (much appreciated!) and were clear about any extra costs. They arranged all inspections, cleaned up after themselves (we were able to move in even before the final vents were in place), walked us through the layout of the walls/electrical/lights/etc and were even able to arrange a dumpster when we couldn’t get one on short notice so we could empty the basement.”—Saul Ansbacher

Reasonable price, no cost overruns, respectful traders

“My wife and I interviewed 4 different basement renovation companies before deciding to proceed with Basement Builders. Our basement renovation project was completed on time (10 weeks form start to finish) and we genuinely believe we made the best possible choice. We got our dream basement exactly to our specifications for a very reasonable price, with no cost overruns/unforeseen additional costs, built with excellent workmanship and great attention to detail. The sub-trades are respectful of our space and good about keeping the worksite clean. The Basement Builders’ owners are quite involved throughout all stages of the project (concept, costing, sub-trade oversight, final walk through) which gave us piece of mind. I would definitely recommend Basement Builders!”—Warren C

2. ReImagine Builders

ReImagine Builders is not just a general contractor for basements but also a seasoned designer. All of ReImagine’s contractors are also trained in the latest building techniques and development protocols for just about any basement build, except basement suites. 

ReImagine’s package already comes with a design consultation, permit acquisition, supply of materials, electrical and HVAC installation, drywall installation, painting, finishing, and cleaning. 

For those who may not be able to afford the best basement reno package, ReImagine Builders provides financing options via FinanceIt.

Among its many good qualities, we find its accountability and honesty the best. These qualities are solidified by ReImagine Builders’s 5-year labour and parts warranty and no-deposit-required policy.  

Additionally, ReImagine offers transparent and straightforward quotations without hidden fees. ReImagine Builders provides such accurate quotations by conducting on-site visits first. 

For safety, ReImagine Builder holds a $2-million-dollar worth insurance liability to secure the best basement renovations in Calgary. 

With all these qualities, ReImagine Builders has even gained an A+ BBB rating, which also tells much about their aftercare and follow-up services. 

The only things we don’t find exciting with this builder is that it doesn’t have a location you can visit and it only operates on weekdays. Luckily, it can work up to late evenings to accommodate busy Calgarians. 


  • No deposit needed
  • 5-year labour and parts warranty
  • Initial on-site visits
  • A+ BBB rating
  • Financing options available


  • Not available for basement suite construction
  • No actual office to visit
  • Unavailable on weekends

Customer Reviews

Cost-effective, exceptional quality, amenable to changes

“We selected Reimagine Builders after meeting with a handful of other companies to explore options for our relatively small basement in northwest Calgary. Bo and his team were not only the most cost-effective option, they also delivered exceptional quality and best-in-class service. Despite the project’s relatively modest size, not once did we feel as though were anything but Reimagine’s top priority. They were very amenable to changes in the initial design of the basement and were in constant contact with us throughout the course of the project to ensure we were satisfied with how things were proceeding. Importantly, they also worked with us to find ways to complete the project more efficiently and were very conscious of the disruption to our family on those rare occasions when their work bled into the evening or weekends. In particular, Peggy and Josh were absolutely stellar – their responsiveness, attention to detail and exacting standards of their subcontractors made the finished space that much better. We are extremely pleased with the result – they helped breath fresh life into our little home, and have given us a space that we absolutely love spending time in (something I never thought I’d say of a basement).”—Spencer Forgo

Regular communication, professional work and advice, attentive staff

“We used ReImagine for our basement development and the experience was great. From planning to finish, they have done good jobs from providing professional advice to attentive work schedules and changes request. Their progress communication were regular and on target. Responses were prompt and clear. Each phase and type of work was done by professionals of that work type and each was done well. The completed basement looks great. Our friends came look and want to have  theirs done by ReImagine as well.”—Paxon Wong

If you want more than just the best basement renovations in Calgary, then Alliance Renovations may be what you need. This contractor does basement, bathroom, and garage renos as well as concrete paving. 

Its renovation covers everything from layout to electrical and lighting installation. Aside from renovation, Alliance can also help with the restoration of basements after flood damage.

Alliance stays true to its name by ensuring smooth communication with its clients, from start to end of the project. Aside from good client relations, this contractor also maintains good relations with suppliers of high-quality materials.

Like its competitors, this contractor is bonded with the Albertan government. But what makes Alliance standout is that it has up to $5 million insurance liability.

Moreover, Alliance has an A+ BBB rating and is a RenoMark renovator. We find that both these measures serve as an assurance of its accountability practices.

However, this contractor isn’t available on Sundays. Luckily, Alliance Renovations has very early opening hours and closing hours on the days that it’s open.

To add to its minor unavailability, Alliance has received some complaints about project management and some about quality of work. 

Although, most of these complaints were for garage construction. And luckily, all complaints, even the basement-related ones, were addressed accordingly.


  • Financing options available
  • Early opening hours and late closing hours
  • Up to $5 million insurance liability
  • RenoMark and A+ BBB rating


  • Unavailable on Sundays
  • Some complaints about project management and quality
  • No on-site initial inspection

Customer Reviews

Mistakes were addressed, polite, helpful, and professional staff

“While the final product is very good and we are enjoying the basement now that it is renovated, during the process there were mistakes and, in some cases, a perceived lack of integrity in the staff and workers. Overall they were quite polite and professional but there were the things above that ruined our experience with the company. We subsequently had a service call from Ryan at Alliance as we had a couple of issues. Even though the issues were not exactly due to Alliance, Ryan was polite and very helpful. Throughout our experience with Alliance, the staff has always been courteous and professional.”—Paul Yuen

Smooth process, informative and responsive

“We are very pleased with the development of our basement.  Jesse, our Site Supervisor, kept things moving smoothly, took the time to keep us fully informed and answered any questions we might have. All the trades personnel did good work. Together this all contributed to giving us a very successful basement development. We would certainly recommend Alliance Renovations to friends who are looking for any kind of renovations.”—Jacqueline Hooper

Additionally, Econo Basements even has WCB insurance to cover any job-related accidents during the course of the renovation project.

Another great thing that we like about this contractor is that it provides a transferable 5-year labour and materials warranty. This also comes with a free 1-year inspection to find and fix any cracks or defects in the build.

However, despite all these qualities, Econo Basements also has its limitations, particularly in its unavailability during weekends.

If you still want to avail of its services, you can simply request a quote online, then the contractor will get back to you within 24 hours. That said, Econo Basements won’t visit your site before making any quotations.

Customer Reviews

Communication is the best quality

“These guys developed our basement over a year ago and we haven’t had any issues what so ever.  The one thing that stood out and impressed us was the communication.  They constantly kept us in the loop and we never had an issue getting ahold of the Econo staff.  Pretty flawless experience I must say, we recommend them to everybody!”—Maria Serpico

On-time and knowledgeable, willing to work with mistakes of previous companies

“It took 3 different companies to get our basement finished, thank you Econo for stepping up!

They were on time and actually knew what they were doing. They fixed all the work from the previous company ( dont get me started) and the final results were my amazing basement !

Thank you Jordan and Econo Basements for all your hard work, well recommend to anyone !”—Michael Denis

What we really find special about Ultimate is that it has a showroom that its clients can visit on weekdays and holidays. So, should you choose them, you can actually see the materials and furnishings before agreeing on them for your basement renovation.
