Signature Construction Service

We are a general contracting company that specializes in custom homes, additions and detached garages. We have been in business since 1998 and have completed projects in Marina Del Rey, Rancho Palos Verdes, Lancaster, Riverside, Corona, Redlands, Jurupa Valley, Perris and Ontario. We are a smaller company and as such we are able to offer competitive pricing and personal service that much larger firms cannot offer. I have built a solid team of subcontractors and in conjunction with them, we work to build a quality project. Our company can take your project from the planning stage through completion.

Review by in Chino, CA
Karl is a straight forward contractor - honest, answers your questions, gives examples, does some of the work himself, but has various subcontractors to handle the rest. Every crew was courteous, worked well together, and had great pricing when compared to other contractor's bids. The project turned out as planned and looks amazing.

Very pleased. constructive advise would be to let the customer know each day if someone would be working on the project. I needed to know to unlock my gate or not. Everyone that sees the shed says it is nice enough to be a bedroom!

Review by in Long Beach, CA
Karl and signature construction did a major remodel of my master bedroom and bathroom as well as reconstructing my kitchen cabinets and adding space saving features in the kitchen. Overall, I thought he did a great job and provided incredible value. Every time I wanted something done differently, he always agreed. He did not go over budget at all, which I was warned would happen, but for me it didn't!. My only gripe about the experience is that it went over the estimated time frame by about a month and a half (and it was a project that was estimated to take 6 weeks). However, all told, we are very happy with the results and would use Karl's services again. I'll also note that he still needed to fix a couple of things and still promptly came back after we'd made our final payment.

Review by in Riverside, CA
I hired Signature Construction Services to convert a bedroom closet into a 1/2 bath and install wardrobes in the bedroom. The end result was better than I expected. I have an older home and Karl's team was able to duplicate the texture of the old walls onto the new walls and harmonize the conversion to look as original as possible. I am thrilled with the end result. Karl and his team are attentive to the homeowner's needs and are courteous and professional. I highly recommend them. Thanks, guys!!!

Review by in Riverside, CA
This is the second project Signature Construction Service has done for me. We converted a closet into an en suite powder room and added built-in wardrobe closets in the bedroom. What a terrific job! I was impressed with the workmanship as they matched the texture of the existing walls onto the new walls and the stucco patch on the exterior of the house (where we closed in a window) was also perfect. Karl's team is professional, courteous and very talented.

Karl and his company did outstanding job on our bathroom. We had an idea of what we wanted, he made suggestions that work incredibly well, and the job was done professionally and well. His bid price was extremely reasonable compared to other bids with no skimping on quality. I highly recommend this company.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
