About Us


The Konstrukt Design & Remodel Philosophy:

Treating our clients like family and wowing them in the process.

Combine excellence in design, construction skills, and knowledge of materials with sound business principles. Set the highest standard – zero mistakes – and the clearest goal – be the best at what we do – and apply them to every project we take on. Build a sterling reputation one client at a time.

It was back in 1952 when Dad first started. He loved carpentry… and he loved people. A simple handshake, and the deal was done. Growing up, my brothers and I were proud that our dad seemed to know everyone and everyone loved him. He left a legacy of working hard and taking pride in what you do. He showed how to build solid relationships with craftsmen and clients that, in some cases, go back decades.

Konstrukt is competitively priced, and doesn’t play “low-ball” games. We’ve created a matrix that gives you a clear sense of what you are investing in, as compared to other options. You’re encouraged to do careful research, but we ask simply that you give us a call and talk to us. Konstrukt doesn’t stage “wine and cheese” presentations like some of the bigger contractors – but as a family, we’ll take care of you and your family.


Our Promise

It’s always about our clients – what their dreams are, respecting their investments and keeping them informed.

Company History
Konstrukt Design & Remodel ("KDR") is a full service general contractor proudly serving San Diego since 1973. We bring years of skill and experience to all facets of construction and building. We perform projects ranging from remodels (bathrooms, kitchens, additions, whole home, landscaping), custom homes, insurance restorations (fire, flood, property damage, 24 hour emergency response), to commercial tenant improvements.

Edward Guerra founded Community Carpentry in 1952 and served the community of Long Island, New York for 20 years. In 1973 Edward changed the company name to Budget Carpentry and began to service San Diego exclusively. In 2003, we incorporated as Konstrukt Development, Inc. Recently, we updated our name to Konstrukt Design & Remodel (KDR) to better reflect the services we provide and how we are found when searching the web. Today, with the reins turned over to his son, John, KDR continues to exceed the expectations of San Diego homeowners and commercial tenants seeking the very best in service, craftsmanship, and professionalism.
Standards for Service

Konstrukt has a proven track record spanning thousands of projects, and representing millions of dollars of client investment. We build confidence in every client relationship by carefully defining their expectations, respecting their property and time, and keeping them informed at every stage of the project.

We set a high bar of performance, and have absolutely NO complaints with either the Contractor’s State License Board or the BBB. The Konstrukt team is well qualified and vetted from top to bottom. We do not hire undocumented workers or those without clean records.

Beyond the long and growing list of satisfied homeowners and businesses we’ve served, our resume includes working for years with some of the most respected and most demanding companies:

State Farm Insurance- The largest insurer in the world. They only work with a small handful of general contractors... and we’ve long been one of them.

Lowe’s- With seven San Diego County stores, Konstrukt was their first general contractor of choice to service their customers.

SDG&E/Sempra Energy- We are the sole general contractor they use for liability claims.

Crawford Contractor Connection- A major insurance and remodeling network serving USAA, Farmer’s Insurance, AAA and many more.

We’ll prove our worth. With Konstrukt, you’re not just hiring a construction company – you’re entrusting your project to a team of experienced pros who have earned their stripes satisfying the most demanding partners – and established an enviable 30-year history of “no complaints.”

Konstrukt Builds Better.
