"Beto did a fantastic job. The stairs are exactly what I wanted. He took great care in building them, was respectful of my property and plants, and totally cleaned up when the job was finished. I will definitely hire him again and I will recommend him to my family and friends."

"Shawn Boyd, Boyd Builders, did a full reno in our main bathroom and did a fantastic job- from floor to installing cabinets, to lining up plumbers and electricians. He managed all timelines. Shawn created a beautiful design around our shower niche and and knee wall. Not only was his work meticulous he is super tidy, which was something we really appreciated. Iâ d say shop no further. We already have jobs lined up for future work with him!"

"Todd was great, he lives close by and was always very attentive, very willing to offer advice and any other help as far as choosing bathroom items, measurements, etc. The project took approximately one and a half months from demolition to completion. Todd was present from beginning to end and completed most of the work himself, he hired out an electrician and a plumber."

"Mike contacted me immediately after my post on Saturday. He worked with me to provide an estimate remotely using pictures and his estimate on cost of supplies and hours of work were very accurate. The quality of the completed work was excellent and he hauled away the old wood and did a wonderful job picking up and restoring the work area. I look forward to using Mike for future work on our home."

FAQs for wood stairs and railings repair projects in Portsmouth, NH

Hiring a pro to refinish wooden stairs means labor makes up 20% to 30% of your total budget. That price covers sanding, staining, and sealing each step. In most cases, a certified refinisher can tackle a 10-step staircase in about two hours, then apply stain and sealant for a durable, eye-catching finish that stands up to daily traffic.

A pro can sand a standard 10-step staircase in roughly two hours, then needs another four to six hours for each coat of stain and sealant to dry. DIYers should budget up to a week for sanding, staining, and sealing in stages. With a crew on site, the bulk of the work is completed in a single day, minimizing disruptions while still achieving a high-quality finish.

It’s possible to refinish stairs without full-scale sanding by using chemical strippers, power buffers, or simply layering a fresh finish over the existing coat. Chemical strippers break down old stains and sealants, while buffers quickly shave off surface material. Even so, a quick hand-sand with fine-grit paper helps the new finish bond properly and look smooth. As always, suit up in protective gear and follow product directions to keep your wood—and yourself—safe.

For most stair projects, you’ll want two sandpaper grits. Begin with 80- to 120-grit to strip the old finish and even out rough spots, then move to 150- to 220-grit for a smooth, ready-for-stain surface. A power sander speeds up the coarse pass, but switches to hand sanding with the fine grit in corners and along edges to keep abrasion even and give stain or sealer something to grab onto.
