    Handyman For Multiple Small Projects

    "Rich is great. He can do just about any project, big or small. He painted my kitchen cabinets, did custom moldings on the kitchen island, installed light fixtures, changed electrical outlets, installed shelving for a mud room, repaired closet shelving, painted and spackled rooms in my house, routed cable wires, did plumbing work in my bathrooms, replaced some broken tiles in my bathroom and hung French doors in my living room. If you can think it, he can do it. He is very reliable and comes when he says he is going to come. Also, his fees are very reasonable. He is top notch and a pleasure to work with."

    "I hired King Kahn Construction to kick off my house remodel and couldnâ t be happier with the result. Justyn met with me multiple times to work through the various design changes I wanted and built my new finished basement. The work that they did was one of a kind and I am so happy I finally have my dream basement to entertain my family/friends and even added a new bedroom for guests. I am already in talks with them on remodeling the first floor of my house and canâ t wait to get started. They are one of the friendliest constructions crews out there and I actually learned a few things myself while going through the process. If anyone needs any work done on their house/business I highly recommend calling King Kahn Construction."

    "My Fiancé and I were in need of a major Kitchen remodel, that being said I had very bad experience when I had my basement redone, the contractor never finished the job and within less than a year what was done started to fall apart. What made that experience even worse it was a friend who was a contractor. Ok now the happy part comes, I went on home advisor to see what I could learn. I contacted Selective Sculptures they had great reviews and testimonials. First Dominic came to my home to see what needed to be done, we discussed our budget and how long it would take to complete. The next step we met at the design studio (mind blown he met me on a Sunday) his ideas were way better than mine we showed him our taste in colors and textures and he pulled off what I can only describe as amazing. Step 2 Dominic came back to the house with Anthony the GM and an entire crew I was speechless the lead plumber, carpenter and electrician went through every aspect with us it was quite an experience to say the least all this for only an estimate. I pulled the trigger if they were scamming me they deserved to get paid they were that impressive. Step 3 Dominic came back with his design plans again I was speechless he came up this a floor plan I one didn't think of or 2 thought possible. I agreed on the spot and was told work would start in 2 weeks and be done in 5-6 weeks. Well half way through what else does one do I was so happy I added additional work tear down the drop down ceiling in living room and do all the hard woods I had no idea I even had (bonus). I would speak to Anthony almost on a daily basis ( I'm sure he didn't love that ) but he was constantly making sure I was happy with progress and had answers for my questions never a let me check on that and not get back to me, in fact twice after I had a question within a few hours he would be calling me from my home so he knew exactly what I was talking about. Step 4 there's always a step 4 the basement's unfinished bathroom again above and beyond they gutted it out and did a total redo. I get a call from Anthony nearing the end as we never discussed color vanity or sink, he says do you trust me I said yes I do and that was the last we spoke of it until its completion he took a nightmare and made it a dream. Our house is now our home I couldn't in my wildest dreams be happier more satisfied or even fulfilled with how all the work was done the professionalism from the entire crew. I am only saddened by one thing and that's the feeling I lost 2 friends in Anthony and Dominic and that's a testimony to them and their desire to customer satisfaction. My name is David Hernandez and I live in Bay Shore NY and from the bottom of my heart I want to thank you SELECTIVE SCULPTURES."

    "I hired DCS to renovate a house for my mother. They had to re-frame walls, move doorways, gut reno 2 bathrooms and the kitchen. They finished the drywall, installed the new tile and cabinets, replaced flooring, and installed a new tile fireplace surround and built a custom wood mantle. Great carpenters. Dick Strine, the principal, is so knowledgeable and thorough. If he can figure out where a problem is coming from in your house, no one can. Great customer service. They have also worked for my in-laws, including building one very large house and renovating another."

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.

You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website. 

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
