Kinds of Work Neighborhood Home Renovation Contractors Take On

Home improvement contractors help you update your home. Essentially, they build on new rooms or structures to the home, enhancing elements including trim or molding, or repairing existing elements like drywall or ceilings.

Some of the services a hometown home renovation provider can deliver include:

  • Expanding your home’s size by adding on bedrooms, bathrooms, or more kitchen or living space
  • Upgrading current areas of the home by adding new counters, cabinets, fixtures, or upgraded features
  • Laying flooring and subflooring
  • Adding finishing details, including painting walls

Because there are a lot of options when it comes to home improvement services, it’s not surprising that a lot of them just cover a few of these options. You might need to work with multiple service providers to get extensive or unique projects done.

How to Find the Best Remodeling Professional in Portsmouth

Picking the most suitable home renovation contractor is the initial step to positive outcomes with a renovation or new home addition. Not all contractors in your neighborhood are identical, and you want to find a contractor with the skills, staff, and time to work on your renovation. After you whittle your list of candidates down by looking at ratings and reviews as well as photos of previous jobs, take advantage of some of the suggestions below to locate the right remodeling company in Portsmouth for your job.

The renovation contractor you hire should:

  • Be certified. Ask prospective remodelers if they possess the certifications for the work to be done. Does the contractor have the legally required certifications and licenses for your area? Is the contractor aligned with any trade organizations?
  • Have insurance. Liability insurance is essential for service providers who come onto your property. Basic coverage protects the contractor and you.
  • Have experience. What length of time has the area home improvement service worker been in business? Companies with the greatest amount of experience are usually the most dependable.
  • Have availability. If a remodeler is busy, it’s a good sign that they’re highly sought-after. Nonetheless, you need a contractor who can promise the scheduling requirements for your job.
  • Be willing to stay within budget. The contractor you select should be willing to stand by the budget you may have.
  • Be authentic. Feedback from former clients is crucial. Check reviews and ratings, and ask for references for short-listed contractors. Pay extra attention to reviews from previous customers with projects similar to yours.

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.

We'd like to replace the oven, fridge/freezer, add a dishwasher, change out the sink and the entire layout of the island and countertops. The bathroom is adjacent to the kitchen and we'd like to remove the bathtub, move the corner toilet, and update the shower size.
