• From the first consultation to the final installation, our experience was smooth, professional, and enlightening. The team took the time to research our property in advance, which made the quoting process efficient and well-informed. During the inspection, they identified an unexpected issue—but handled the repair quickly and with zero hassle. The only hiccup was with scheduling, as there was some uncertainty around timing. However, the quality of work more than made up for it. The installation was flawless, the crew left the site spotless, and the finished result exceeded our expectations. Highly recommended for anyone seeking skilled, reliable service and top-tier workmanship. A solid 5-star experience.

• Custom Contracting recently installed new sliding windows, a patio door, and HVAC system at our home in Guelph, and we're thrilled with the results. The installation team was professional, courteous, and extremely careful with our property. The new sliding windows and door look fantastic, operate smoothly, and greatly improve our home's comfort. The HVAC upgrade has noticeably improved our indoor air quality and temperature control. Their pricing was transparent and fair, and we appreciated their honest, pressure-free approach. Highly recommend Custom Contracting for reliable, high-quality home improvement services!

  Rahib C.★★★★★

• We recently hired these guys for roofing and HVAC services and are extremely satisfied. The team was professional, efficient, and delivered exceptional work. Their "lifetime warranty" is genuine, and our neighbors even got a $500 gift card through their "new neighbor program." Plus, their referral program offers up to a $5,000 bonus. Highly recommend!

  Jemish S.★★★★★

• Custom Contracting Guelph just finished our eavestroughs and HVAC, and earlier this year they did our roof too. Same great service every time. They worked fast and cleaned up every scrap. Roof came with a lifetime warranty, plus we got a rebate and easy monthly payments—huge help. Eavestroughs look sharp and the new HVAC keeps the house comfy and quiet. Fair prices, honest advice, zero pressure. If you’re in Guelph and need roofing or home-comfort work, these are the people to call.

  Tanvi S.★★★★★

• Custom Contracting handled our roof and eavestrough repairs in Guelph last month, and the whole process was straightforward. From the first call, Chris was prompt with a clear, written estimate and walked us through the materials without any sales pressure. The crew arrived right on time, laid down tarps to protect the driveway and garden, and did a thorough magnet sweep when they wrapped up. The new shingles look sharp, the flashing lines are tidy, and the gutters finally send water where it belongs—no more overflow over the porch. They finished a day ahead of schedule, kept us updated at every step, and the final bill matched the quote to the dollar. If you’re in Guelph and need roofing or eavestrough work done professionally, Custom Contracting is an easy recommendation.

  Kartik G.★★★★★

• Custom Contracting did our roofing and eavestrough repairs, and the whole process was smooth and professional. They clearly explained all our options, provided a detailed quote, and never pressured us. The team arrived on time, did a great work, and left everything spotless. The shingles are perfectly installed, the flashing is clean, and the eavestrough now works flawlessly. They even finished a day early. If you need roofing or gutter work, I highly recommend them for their great quality, honest service, and a tidy job site.

  Parimal N.★★★★★

• Custom Contracting just finished replacing our shingles and fixing a stubborn eavestrough leak, and the whole experience was refreshingly smooth. Chris explained every option in plain language and gave us a clear written quote—with zero sales pressure. The crew showed up right on time, protected the driveway and garden beds, and swept up every last nail before they left. The shingles sit perfectly flat, the flashing is tight, and the gutters now drain exactly where they should. They even wrapped up a day ahead of schedule. If you’re in Guelph and need roofing or eavestrough work, these are the people to call. Quality craftsmanship, honest communication, and a spotless job site—can’t ask for more.

  Zala Y.★★★★★

• Very sketchy company. They claim to be located at 17 Cork St. W. in Guelph and they are not and never have been at that location. Google the address and you will see that the law firm of Jackman & Rowles is at that location. It has been a law office since the mid-1970's.

  Cal R.★★★★★

• Good value and quality. Sales approach was great. There were some hiccoughs on communications and minor install mistakes. They made it right and then some by fixing them quickly and replacing the gutters on my shed at no cost.

  Tim D.★★★★★

• Austin was great to work with, very professional. Very happy with the gutter installation, wouldn’t go anywhere else!

  Moe S.★★★★★

• Not only am I happy with the completion of our eavestroughs. Austin was a very pleasant and easy sales rep to deal with. Ask for him!

  George L.★★★★★

• I can highly recommend Custom Contracting to everyone and would happily use them again. Even though I only needed a relatively small repair done, it was no inconvenience or a problem for them. Matt arrived on time as arranged to inspect the job and he did a great job of doing the repair leaving everything neat and tidy.

  Shawn E.★★★★★

• CC is always so happy to help. They were happy to answer any questions and genuinely cared about me as a customer. I recommend them to everyone.

  Nick C.★★★★★

• Would use this company again, very professional, excellent communication, quick Eavestrough service. If you need your Eavestrough replaced these are the people to do the job. Would definitely use again and am more than happy to recommend them to others.

  Mariette J.★★★★★

• From beginning to end, this company were fair, friendly, professional, and swift. I highly recommend them.
