  • Nancy & Gary Anhorn,

    Recommendation Letter for Mike Leeds Sandstone Associates We have recently had our main bathroom renovated by Sandstone Associates.  The planning and execution of work was performed with a very high level of quality.  We currently are in the process of receiving an additional renovation quote for our master bedroom ensuite bathroom from Mike.  This in itself shows the satisfaction we have with our current renovation. Nancy & Gary Anhorn

  • Simon & Marilyn Lai,

    "We worked with Mike to renovate our kitchen. It is a small space and needed a dramatic update. Mike took all of our ideas and managed to transform them into reality with very little issue. Anything that did come up was dealt with quickly and headache free; as Mike did all the coordination with the sub-trades. The work was completed in a timely fashion and, in the end, we actually saved some money! Boom. Our experience with Mike was overly positive and I would have no issues hiring him for our next project. I've also been telling all of our friends/family about his services who are thinking about starting a reno project."

  • Stephanie & William,

    I would highly recommend Mike for any renovation project. I initially called him because his company Sandstone Associates is listed on the RenoMark website and because of his slogan, “We are Stubborn about Quality”. We had two projects completed; our front porch was beautified with the installation of new boards, white lattice and a cast iron railing, and our 1980s washroom which had numerous plumbing issues and cracked shower tile was completely gutted and redone. I absolutely love the matching tile work in the shower and the vanity backsplash. Mike did an excellent job detailing all of the costs associated with the two projects and we even came under budget! I also really appreciated how Mike returned my emails and phone calls promptly whenever I had questions. He is very knowledgeable and reliable, and we will definitely request his services next year for another major renovation project. –Stephanie and William

    John, Mike & Rob, We are pleased with the quality of the work , and we have already had two sets of guests stay in the new bedroom!  If you require reference for future jobs, you may refer clients to us using our home phone numbers. Regards, Les & Liza

  • Dan & Katy,

    We had a renovation done after purchasing a 50’s era home late in 2013. Mike was very proficient in providing a quote and an estimated timeline. The final project was finished within the timeline and below budget to a very high standard of quality. When it comes to home renovation, you can’t ask for much more than that. Thanks for the great work Mike. It is our pleasure to provide a positive reference to any of your future customers.

  • Dave & Marion,

    Mike Leeds was the general contractor for our main floor renovation. Demolition, hardwood installation, painting, trim work and a new kitchen (cupboards, sink and taps, counter tops, fridge, stove, dishwasher) was installed. Mike kept us informed and did what he said he would do and when he said he would do it. He kept us informed at all stages. If something came up which was not in the contract, Mike gave us alternatives. We would highly recommend Sandstone Associates. Dave and Marion Main

  • Gonsalves,

    We hired Sandstone to do an extensive kitchen renovation including cupboards, countertops and knocking down a wall. Sandstone also did a full bathroom renovation from floor to ceiling, fireplace removal in our living room and ceiling paint and refinish on our main floor. Mike was referred to us by friends and was described as being "on time and on budget" and he very much lived up to this description. Mike made us feel comfortable throughout the process, was open to working with us on the pricing and was highly trustworthy. He was helpful in selecting vendors and his subtrades did an excellent job and kept the house broom clean every day. During the renovation, our bathtub was chipped and Mike replaced the entire thing for us. Partway through the renovation, a pipe burst on our main floor (through no fault of the renovation) and we were out of the country. Mike and his team went above and beyond to help us during this time and Mike still made our renovation a top priority when working around the delays this caused. We would highly recommend Mike, and already have to many friends, for any renovation. We are beyond happy with our new home.

  • Curtis,

    I have worked with this company on two separate renovations in two different houses and would not hesitate to hire them again if/when we do further renovations. We first worked with Sandstone in 2010 on an extensive renovation which included two bathrooms, hardwood installation, exterior, deck, carpet, trim and paint. Mike and John were great to deal with and the work that was done was very professional. The second renovation was a bathroom in 2014. This renovation was done ahead of time and once again the work was extremely professional. Mike was very good at keeping me informed of progress and what work was happening when. I am very happy with the end result of all the renovations done.

  • Delia & Rob Langstaff,

    Feb 12/2014. Letter of reference, for Sandstone Associates, Mike W. Leeds. It is my pleasure to write a letter of recommendation for Mike Leeds, of Sandstone Associates. Nov , 2013 we contracted Mike to do our home renovations, which included, painting , full kitchen replacement , flooring on our main level, hardwood , carpeting and tile, master bathroom, baseboard and window trim. Mike did a cost estimate for us in advance which was accurate with room for upgrades and changes , and provided a timeline for work and expectation for what would transpire.  With minimal variances. Mike was professional as were all the trades people he brought in. The trades people all spoke highly of Mike and respected the time frames that he laid out. The work was completed early and very much to my and my spouses satisfaction. The professionals that were contracted in made recommendations that helped make our choices easier. We are now enjoying our newly renovated home, and didn't have to move from our neighborhood. When renovations are done professionally, the short term inconvenience is well worth the final result. Thank you Sandstone Associates.. Mike. Yours truly, Very satisfied clients, Delia and Rob Langstaff.

  • Martha Hughes,

    Dear John & Mike, Thank you for the wonderful job you and your crew did on our downstairs bathroom.  We were very impressed with the speed and competence your people demonstrated and their overall abilities in controlling the mess. There were a lot of things we learned in the process; some things I'd change and some things I'm glad we didn't change. I hope we weren't terrible clients and I hope to repeat the process a little further down the road. Again, thank you Martha Hughes
