"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."

"From our very first meeting I knew these were the right people for our project. We added a second story to our home in El Monte and they designed it so beautifully that it doesn?t look like an addition at all. Neighbors keep asking who our architect is."

"Excellent experience again with Alpha Structural. Charlie Rosenkranz came to see the 3-story apartment building in West Hollywood. We discussed what the soft story retrofit plans will likely include. He's knowledgeable and experienced. We appreciated his professional no-pressure approach and answering our questions. Alpha performed an exploratory investigation of the support structure, as architectural plans were not available. They engineered the plans with city approval. They then consulted with us and provided the approved THP (Tenant Habitability Plan) paperwork. Production Manager Dave Schlaich and Job Supervisor Seth Price met me before construction. Dave went over the approved plans and explained the work that would be performed, and the purpose. They both answered all my questions. Lawrence and Antonio were the main work team. They were very pleasant and answered all our questions. Both had great explanations with Lawrence being very detailed. Seth provided timely progress reports by phone and text. He answered all questions, and provided contacts for automatic shut-off gas valves and stucco work. Despite Covid-19, they scheduled and passed inspections, and completed the work in under a month. We've seen projects by other companies stuck in limbo for months with no progress, so we chose Alpha to avoid complications. They removed all debris, and left the property clean. The tenants and neighbors had no complaints. Daniel Aparicio also explained various issues. Communication with everyone, including the office staff, was excellent. We're very pleased with this experience."

"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

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"They did an excellent job. I talked to the owner, Conrad, through the whole process and he gave some beautiful suggestions. I would highly recommend them and I will definitely be hiring them again to do more work for me."
