What clients say about MDG Builders
Emil did a renovation of our bathroom on a short notice and completed it within the time we needed. He did a very wonderful job with great attention to detail and I would definitely work with him again on future projects! He walked us through how to pick materials and provided feedback on some of our initial material selection (thanks so much from saving us from potential future headaches!) and worked with us on our budget. He was also very trustworthy and easy to work with.
From the beginning, we had a great experience with the team at My Design Guide Inc! We wanted to upgrade our patio but we weren't creative enough to know what to do. David was full of great suggestions to make the patio a true conversation piece while still honoring our budget and we couldn't be happier with the result! The quality of work and professionalism is the best I have seen in this business, and they really do take pride in their work. David communicated with us throughout the process and was meticulous in ensuring our yard was still taken care of during the construction period. We have received so many compliments on our new paver patio, fire pit with seating, and built-in outdoor counter. I highly recommend going with them. I would go with them again a hundred times over!
We had no idea where to start, we had a large project with so many moving parts can be very challenging for novices like us. From the very beginning, Emil was responsive, helpful, timely with any questions, night and day. Since this was a gut job we were even more nervous. We were astonished on just how easy the whole process was with no hiccups at all. Less than 3 weeks and we had a wonderful spa. His workers were responsible, timely, responsive and did an amazing job down to the little details. Even our friends were surprised we had such an easy time with the job. Book them for any job because you will not be disappointed.

Cost guides:
How much does a bathroom remodel cost in Southern California?
Typical installed ranges are about $12,000–$25,000 for a refresh, $25,000–$50,000 mid-range and $50,000–$100,000+ high-end.
How long does a bathroom remodel take?
A cosmetic refresh can take a few weeks; full renovations take longer and depend on permits and material lead times.
Is a tub-to-shower conversion worth it?
For many households a walk-in shower is easier to use and clean. It typically falls in the mid-range band.
Can microcement go over existing bathroom tile?
Yes, in many cases. Sound, well-bonded tile can be prepared and coated, avoiding demolition. Loose or cracked tile must be repaired first.
What adds the most cost to a bathroom remodel?
Moving plumbing, custom glass, natural stone and custom cabinetry are the biggest cost drivers. Labor is often 40–60% of the total.
Do I need a permit for a bathroom remodel?
Generally yes when plumbing, electrical or walls change. Your local building department sets the rules.
What is the cheapest way to update a bathroom?
A refresh that keeps the layout: new vanity, fixtures, lighting and paint, or resurfacing tile with microcement.
