"Full kitchen and bathroom remodel. (Loft condo) From my initial meetings with Anar the owner, to meeting the team that did the install It was an entirely stellar experience. Anar presented me with samples and a clear understanding of the project scope. A project manager was assigned that came out to the site on a regular basis to monitor progress and quality. The two gentleman that came out to do the installation were personable..and maintained a clean workspace and professional attitude throughout. Both obviously skilled for the job duties. There was great care taken during the project on communication regarding the installations, and leaving the site as undisturbed as possible (clean) and with respect to property rules. (Condo). The fixtures and materials offered were all top quality and brands. Project oversight and city permits were all handled by the project manager. A very high level of communication and attention to detail were provided throughout the project. My spouse and I are very happy with the results, and this is added tremendously to the value of the property. This is our first remodel, and although it is an inherently stressful undertaking, Anar and his team really delivered with service and quality. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ gentleman! Thank you again!

System Pavers is the nation’s leading outdoor remodeling company, thanks to award-winning customer service and more than 30 years of experience behind every install. With every project backed by industry-leading warranties, over 90,000 homeowners have trusted System Pavers to create beautiful, easy-to-maintain outdoor spaces where family and friends can connect for generations. System Pavers’ visionary designers and expert installation teams specialize in hardscapes, patios, driveways, turf, outdoor kitchens, BBQ islands, water features, fire features, decking, and more.

"A year and a half ago, we hired System Pavers to redo our driveway: changing it from stamped concrete to pavers. At the time, we knew we wanted to do the same thing to our back patio, but we figured it would be smart to try them out on a somewhat smaller project first, and then tackle the much larger and more complicated back yard once we knew we were satisfied. (Back yard is ~2,000 sq ft.) Needless to say, we were delighted with the work they did in 2019, and therefore asked to have the same project manager (Jimmy Jackson) again this year. That said, Jimmy had a long weekend planned out of town during our project, but things continued without a hitch, with Rich Daugherty stepping in to cover in Jimmy's absence -- absolutely seamless service! The project started ~2 weeks ago, and was completed in only 10 working days, including one Saturday (at our request -- so as to get the noisy jack hammering all done in as few business days as possible). Note that my husband had delayed moving forward on this project because he guessed it would take them a minimum of 4 weeks to complete it, with at least 2 weeks of jack hammering the old concrete. Wrong! It was more like 3 days of demo, followed by 7 days of construction -- and the demo all had to be done by hand: there was no way for a bobcat to access our back yard, so the guys used jack hammers and wheelbarrows to remove all that concrete. They are are FAST! They are also artisans: our house is of modern design, so the pool and back patio have lots of corners, which were mitred beautifully. They also added drainage to the patio, thereby solving a prior problem. The detail work was simply awesome! Any question we raised, they addressed, and we saw Jimmy or Rich here daily, ensuring that everything was picture perfect. Believe me, if/when we have any other hardscape that needs attention, we will call them again!"

FAQs for second story addition building service projects in Northridge, CA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
