"The work the boys did from removing the old deck to rebuilding the new deck was very efficient and very well done. The communication about the timing of the days when they would come to work was not accurate. However the job was finished and the deck is complete."

"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

"I had a major water flood disaster in my kitchen [punctured ice-maker-hose] that destroyed my hardwood floor and leaked through to the ceiling below damaging the ceiling, walls, backsplash, and countertops to my second kitchen below. The insurance company sent a recovery crew to dry out the floor, ceiling and walls; mold had set-in due to the hot & humid July 2022 temperatures. My insurance company recommended I continue with the recovery company to have my property restored but they were booked 6 weeks-out! I have a frail elderly mother that lives with me, I needed my kitchen back ASAP. John Ryan Construction came highly recommended by a friend. John personally came out to assess the work and by weeks end his crew was working on restoring my kitchen(s). John's crew found mold on the backs of the cabinets that the recovery company missed. His crew used Micro-band to clear the mold from the back of the cabinets. My kitchens are fairly new, 2018 & 2020. However, John's crew found several short-cuts in the installation of my kitchens that his crew corrected. John has a complete crew of highly skilled professionals: carpentry, electrical, flooring, granite-counter-install, plasterers, tile-work... I was blown away by his crew! They worked efficiently and conscientiously to complete the job, showing up on time and cleaning up at the end of each day. My kitchens are restored to better than what they were before the flood! John Ryan Construction was able to work with the budget set by my insurance company's claim. In 3-weeks-time John's crew had my kitchens back to new...I am so grateful to John and his crew!"

FAQs for contractor service projects in Portsmouth, NH
Generally, general contractors charge between $50 and $150 hourly, though not every contractor charges by the hour. If charging based on the project, you can expect a markup of 10% to 20% of the construction cost. You can expect to pay between $300 and $500 daily if charged by the day.
General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:
Complete pre-construction planning, both with the customer and crew
Provide realistic cost estimates
Develop construction timelines
Ensure deadlines are met
Acquire permits as needed
Purchase supplies and materials
Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:
Which types of insurance do you carry?
Can you provide a list of references?
What is the expected timeline for this project?
How will my project be supervised?
Will you hire subcontractors for the job?
What is the best way to communicate changes?
Will you obtain all of the required building permits?
While city and state laws vary on general contractor licensing requirements, hiring an unlicensed general contractor could lead to poor quality work, costly future expenses, and potential code violations. Be sure to check our state licensing tool to review the local general contractor guidelines for your area.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
