    Welcome to Solarium Repairs. We specialize in repairing solarium's and helping prevent future issues. We offer services with integrity and to ensure customer satisfaction. Solariums, Conservatories, Sunrooms; they are sold under many different names by many different companies. Some of these companies are still around, some are not. Some of these companies had great carpenters but not so great glaziers. We at solariumrepairs.com have been in the glazing business for 25 years specializing in servicing sloped glazed systems. We do not build new Solarium's but have great relationships with people that do. We are firm believers that these rooms live with the environment, and the environment continually changes to the detriment of these glazing systems. We service many clients that have been orphaned from the original suppliers of their rooms and thought they had nowhere to turn. The rooms require a tradesman to have many defined skills to carry out the work to the quality expected. We provide carpentry,finished carpentry,caulking, metal work, and drywall and of course high end glazing. Please feel free to contact me. Andy Lansdown 647-567-5449

    Hello, my name is Dumitru, and I’ve been in the carpentry and renovation world for over 25 years. My journey started in Europe, where I spent 7+ years mastering fine carpentry, and for the past decade I’ve been proudly serving homeowners in Canada. I believe in true craftsmanship, attention to detail, and, as they say here, going the extra mile (sometimes two) to make sure every client is happy. Quality is not just a word for me; it’s a promise. My clients know me as the guy who always finds a solution, no matter how tricky the project might be. I speak English, Spanish, Russian, and Romanian, which often comes in handy in Toronto’s wonderfully diverse community. If you’re looking for someone who treats your home like his own and values craftsmanship as much as you do, I’d be happy to help bring your project to life.
