I found The Affordable & Licensed Handyman through Yelp because they had great reviews so I was interested to see how much their service fee would be for a simple job when I was looking for a plumber. I needed a license plumber due to home insurance requirement to do this installation or I would've done it myself. They were responsive when I talked to them through Yelp projects. I was shocked with how much I was quoted because it was almost double the price of the automatic shut off valve device I paid for. So I had to confirm that the price that was given to me was just to switch out the bad unit with the new one. They didn't have to do anything else like run new pipes or replace anything else. When I communicated to them that the quote was high, they asked how much did i wanted to pay. I thought they would try to be more reasonable since the name is The Affordable. I give them a range based on the prices from other plumbing company that I reached out to and they couldn't do it which I understand they can set their own prices. Maybe for big projects, they'll give more of a reasonable price which is why they have great reviews on Yelp but just to replace a bad automatic shut off valve with a brand new one, I think it was overprice so I used another plumbing company where they were very reasonable on the price.

Robert came in, assessed the issue, and got to work. Within a couple of hours, everything was functioning properly again. If you have more complex or modern fixtures, he's definitely someone worth calling. Fair pricing, good communication, and clearly knowledgeable about this type of work.

    I'm not sure where these good reviews come from because my experience has been the opposite. We had…read morea brief chat, he seemed busy and wanted pictures sent to him directly instead of actually coming by in person to do an actual inspection. I've had at least two others come by, one of them hasn't given me a quote, the other had followed up and I did receive a quote from them. I can't say the same for this guy, he just left me on read and never bothered to follow up. I'm not going to go out my way to pay someone and give them an opportunity because it's not my job to go after people and to follow up. Also if you're more "value orientated" like me, he has a $550 a day minimum so keep that in mind. It could be that my job didn't hit this so he couldn't of bothered, but I am just speculating. The process to find a reliable contractor is a quasi part time itself. All of them are situational and with that being said, it's a huge YMMV based off when you need or want them and if they will even bother to entertain you because they just don't care enough to follow up if its a bad time (Which you'll never know). There's a happy ending to this story though, one of the people did get back to me and I just need to figure out how to schedule him when we figure out how we're going to get things done. This is all the time and effort I will put into this.

Ailyn came by to take the initial inspection of work and was very friendly. She took measurements and was able to speedily prepare an estimate for the work. They were willing to work with my schedule even though they are fairly busy. They communicated very well throughout the whole process and kept me up to date even days leading to the job date. Ailyn and the framer were prompt and on time. They go to work and delivered exactly what they said they would. Franklin made a stop by to also check on the progress. Day of, I even had a 3rd area of concern and they were willing to also complete this as well with no prior heads up. They go out of their way to accommodate and execute. They even helped with replicating the decorative facia around the post to match what was originally there. They were very reasonable and fair with their pricing. They also completed the job in the time frame they committed to. I look forward to utilizing them for future projects and repairs. Thank you Villatoros!

Two wouldn't take the job because it was too small. Franklin came by and gave me the best price. After the initial deposit, his crew came by about a week later and finished the job in one day. I think they did a pretty good job replicating what had existed before, although the work seemed a little sloppy. I saw a few gaps in the framing, but they were able to seal it up with bondo. Also on one of the posts there was a large crack in the wood, but that was sealed as well. For the price, I think this was a pretty good value. Would definitely recommend for smaller jobs like mine.

He and his team made sure everything was well supported and working properly before and after installation. We felt comfortable leaving the house for work, etc. knowing our home was in good hands. We decided on custom cabinets which Cavalier built and installed. The quality is excellent and the stained wood on the lower cabinets look stunning. The tile work in the bathrooms and kitchen are also top-notch.

You can tell they take great pride in what they do and actually care about their clients. I like that they're a family-run business as well. This was my first attempt at investing in a rental income property and was very nervous about finding the right contractors to do the job well, for a fair price. I received several other quotes, but so glad I chose CB. David Moshe was my main contact there. He was knowledgeable, friendly, and straightforward about what needed to be done and where potential problems might be. From day one, everything went smoothly and efficiently. I was given a clear work timeline and payment schedule. Was informed about each step as they progressed. It was a tremendous amount of work to be completed in 3 months, which they did. David was patient and understanding with my many requests and questions, and immediately solved any issues that came up. Wish I knew all the names of the crew as well. They were all highly skilled, professional, and respectful of my property. I wouldn't hesitate to use Cavalier Builders for future projects and highly recommend them as well.

The project involved a lot of layout decisions, uneven floor conditions, outlet coordination, panel proportions, cap details, and making sure everything would work both visually and practically in a commercial space. Paul was thoughtful throughout the process and clearly knows finish carpentry. What I appreciated most was that he did not just rush through it. He took the time to think through the details, explain options, and flag things that could affect the final result before cutting into the material. He was especially careful with the panel layout, wood movement, grain direction, and how the base and trim should be handled so the finished product would both look right and hold up well over time. The wainscoting came out really elegant and clean, and the craftsmanship is obvious in person. It gave the space warmth and character immediately. The bar work also came out great and tied in nicely with the rest of the room. Paul cares about the end result and it shows. If you are looking for someone for detailed trim or custom millwork and want somebody who actually thinks through the job instead of just nailing things up, I would absolutely recommend him.
