September 21, 2024 Jonathan and his crew did a fabulous job fixing our sunken garage and foundation cracks. They were very quick to respond, did the job extremely well and very quickly. I would recommend them in a heartbeat!

Detailed reviews
August 12, 2021 Poor experience with them. Misquoted then claimed I was responsible for their mistake and to finish the job was another $6000. Didn’t include stress relief cuts in the quote said it also was an add on. Said Drainage system would be done as per discussion then changed it to save them time and labour. Formed outdoor slab so rain would go under slab not on to. Had to fire them in the end. Left garbage in the end, screws just thrown on the ground
March 15, 2019 Working with Jonathan for me was exactly what I believe working with a contractor should be like. Jonathan excellent understanding of his trade, not only technical, but artistic (The finished look) was exemplified in this job. Jonathan communication on this job was above and beyond what I have experienced with all other contractors in the past. The project was handled professionally from start to finish. I was most impressed with the job site cleanliness. Highly recommended
June 28, 2018 I definitely recommend Jonathan and his crew! Professional, clean, punctual and fair pricing.
September 11, 2017 Very honest, professional and hardworking guys. The job looks wonderful!

What to check before you hire
Worth checking yourself
Only a few public reviews are shown. Ask for recent references you can contact.
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire.
A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay.
Look for consistent reviews across several named sources, not one polished profile.
