4.0 Anita r. P. Livermore, CA

The workers did a great job. It's been a little hard to reach Sebastian, because he's so busy. He gave us an honest price and his crew was very professional. I would use them again. Anita

Response from Company:

I do apologize. I cannot understand why I forgot to pick up my final check from you. A lot of my clients just put the check on the mail or remind me via text or a call to pick it up, my sincere apologies, I will collect from you in due time next time since you would hire us again. Thank you for the thrust you have placed on us.

5.0 Aldrin M. Hercules, CA

Sebastian was very professional and did a great job for the job I hired them for. Sebastian and his crew fixed my window trim and siding.

5.0 Joanna A. Pleasanton, CA

I bought my first home and was very thorough and cautious in my search for someone who wasn't going to take advantage of my lack of knowledge with home remodeling. After meeting with multiple contractors, I decided to go with Sebastian because he seemed like an honest, hard worker. Casablanca Construction helped renovate my entire condo to exactly what I wanted at an affordable cost. I am picky and I had a specific vision in mind and he made all my wishes come true. Thank you Sebastian & crew!

Response from Company:

Thank you for the opportunity you gave us to work for you, thank you for the coffee!

5.0 Alejandra R. Union City, CA

Dry rot repairs - had 3 estimates before Casablanca Construction. Sebastian was personable yet very professional and HONEST. We (older and knows nothing about repairs) need people like him. Pointed out possible future damages (no pressure). Have very polite, hard working crew especially Martin. Good quality of work for a reasonable price. I would definitely recommend them.

Response from Company:

The least I can do is say thank you!

5.0 Lori R. Pleasanton, CA

Casablanca Construction replaced all of our windows and trim and about 25-30% of our damaged/aged siding. We were given a written estimate. The men on our job site were extremely hard working and very polite. They showed up every day between 7:30 and 8:00 am and often worked until 4:00 or 5:00 pm. Even when the owner was not on the job site, the crew worked hard and kept the job on schedule. This captured the attention of three of our neighbors who also ended up hiring this company to replace siding. If something extra needed fixing, they just did it! The owner, Sebastian, is very honest and humble. He treats his crew with respect. We plan to hire this company again within the next year to remodel our master bathroom.

Response from Company:

Thank you Lori, we must be doing something right lately, we are working for the nicest people, thank you.

4.5 Ed H. San Leandro, CA

This contractor accepted the job, which another contractor refused because it was too small. Everything was done professionally, including a signed contract, high-grade materials, and a pleasing result.

Response from Company:

Thank you Ed, your small job helped paid for one of my guys bills, him and I appreciate that, thank you!

5.0 Yasmin V. Bell Gardens, CA

They designed and built my new home. At the beginning the process was a little rough but soon after a conversation with the owner the whole building process was top notch! Extremely impressed by the great quality of work and very professional people.

Response from Company:

Thank you Yasmin, the process of building a house could get a little rough but I took care of your concerns in a professional, timely manner, thank you!

5.0 Claudia R. San Jose, CA

After contacting several contractors to bid on a 500 sq ft addition, we decided to hire them after meeting the owner. Very honest, humble, not the cheapest, but we are extremely happy with their professionalism!

Response from Company:

Thank you for your nice comments, we enjoy doing what we do, I am happy your happy with the end result, thank you, the least I can do!

4.5 Mickey R. Los Altos, CA

Response from Company:

0.50 Steve P. Newark, CA

When I contacted casa blanca const. They had no idea who or what we were talking about (that is after the job was started). However, the person that was doing the job showed up to correct my concern. I do not appreciate the lies... or the way they handle their phone calls.

Response from Company:

I have a lot of respect for people of all ages, HomeAdvisor and us still don't know what happened except what you told me personally, when we completed the repairs, you asked for a 10% discount, you said you called Yelp and they told you Casablanca would give you 10% discount, well, we don't advertise with Yelp, I don't like yelp at all, I never have had a promo of any kind, I'm glad you gave them a 0.5 customer service review, I would've given them a -0 on customer service, we got to you through Homeadvisor not Yelp, you called us that we had left a hole on the wall, I showed up within 24 hrs to fix it, you answer the door and apologized to me, admitted you made a mistake that it was dark and could not see right, your wife called me to apologized for you, I accepted her apologies and moved on, but you didn't, you clearly were calling Yelp and HomeAdvisor at the same time, Casablanca through HomeAdvisor showed up on time, did the work as promised, got paid, thank you, you mentioned we showed up to take care of your concerns right away, that's what we do, at the end of the day you pay our bills, I think your comments are malicious and misleading, but nonetheless I thank you for the 4.0 quality rating, will never forgive yelp for creating problems for us, even when we are not affiliated with them in any kind, shape or form! never will!

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.
