"The experience of working with Pristine Construction greatly exceeded my expectations. At least one of the owners was on site every day, and from the moment construction started they did not skip a day of work. Everybody was friendly and knowledgeable. I can't imagine hiring another company in the future."

"Structural engineer came by to confirm if wall was non-load bearing as suspected. Confirmed, can now move on with my project."

"Couldn't be happier with the project from start to finish. Same day quote, with work following quickly after that. Tile installer was outstanding."

"Franco and his father Rene are experienced architects who came out to the site promptly, game planned a way to get approval for a multi unit triplex from duplex on the spot, and followed through each step of the phase. We successfully were able to get all city approvals in the city of LA. A+ Rating"

"I recently hired G&L Design Building and Landscape for a major outdoor project, and I couldn't be more thrilled with the results! From start to finish, the experience was seamless, professional, and truly impressive. Dror, the owner, is a visionary. His attention to detail, creativity, and commitment to quality were evident in every phase of the project. He took the time to understand my vision and brought it to life even better than I imagined. His team built a stunning retaining wall, installed lush, vibrant turf, and laid down beautiful interlocking pavers that completely transformed the space. On top of that, they planted an incredible selection of trees and flowers that added the perfect finishing touch—absolutely breathtaking! The crew was punctual, respectful, and worked with great care and precision. It’s rare to find a team so dedicated and passionate about their craft. If you're looking for top-tier landscaping and design, look no further than G&L Design. Dror and his team are the real deal—professional, talented, and a pleasure to work with. Highly recommended!"

"David and his team did a great job with the drawings for our room addition remodeling project. We added a large section to the back of the house and created a 1 bedroom and a bathroom room with a small kitchen. David came up with comprehensive blueprints for the entire remodeling project, and he also generated a great 3D renderings of the addition for us. He also got for us all the permits from the city."

"The landscaping and landscapers did a fantastic job. Never was pressured to do more than I wanted. Their ideas suited the needs of what I asked for."

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"Kn remodeling and supplies did an excellent job, which consisted of remodeling two bathrooms, the kitchen, two bedrooms, living room, dining/bar area, and upgrading the garage ceiling.

This townhouse project included stripping wallpaper (5+ rooms), painting throughout including staircase walls/ceilings and all the doors and closets, baseboards, toilets, bathrooms shower doors + associated plumbing hardware, bathrooms tiling, and cement-board floor replacement of linoleum in the kitchen + bathrooms.

During this process, the crew took great care not to damage pre-existing items in the house, including the hardwood floors and others. They were very attentive, courteous and professional, and importantly responded to our needs for some scheduling accommodations.

Debris removal/collection was conducted daily, allowing us a welcome degree of relatively unobstructed normalcy during and (especially) after work-days, as the multi-week project progressed. Dust-protection of floors, staged items and furniture was well-implemented, with residual particles (floaters) needing post-remodeling attention.



I want to thank Nathan and KN Remodeling
