Exterior painting in New Hampshire
Siding, trim, doors and other exterior surfaces for homes and businesses, cleaned and prepared before the first coat. Brush, roller or spray, whichever suits the surface. Handled by JT Paint since 2017.
What is included
What does an exterior painting project include?
Exterior painting is a project where the weather, the age of the surface and the preparation all matter at once. The outside of a building faces rain, snow, sun and wind, so the work is more than a color change. It is cleaning, repair, protection and a finish that has to hold up outdoors.
JT Paint handles the full sequence for residential and commercial properties: washing the surfaces, repairing and preparing them, protecting the property around the work and applying the finish with attention to the details people see from the street.
- Siding and exterior walls
- Trim, fascia and exterior doors
- Power washing before painting
- Scraping, patching and surface preparation
- Wood and metal coatings
- Spray application where the surface calls for it
Step by step
How does an exterior painting project run?
The same standard on every job: show up when expected, communicate clearly, protect the property and finish with attention to the details.
Walk through the project
Which sides of the building, which surfaces and what condition they are in. You tell us what you have in mind and we talk through what the job involves.
Clean and protect
Surfaces are power washed so the paint meets a clean base. Plants, walkways, windows and anything not being painted are protected.
Repair and prepare
Loose paint is scraped, damaged areas are patched and bare spots are made ready, so the new coat has something solid to hold on to.
Paint and check the details
The finish goes on by brush, roller or spray. Then the details get checked: edges, trim, doors and touch-ups.
Know your surface
Which exterior surfaces need which preparation?
Not every surface is prepared the same way. Wood, metal and previously painted siding each behave differently outdoors, and that changes what happens before the first coat.
The table is general guidance. What your surfaces actually need is something we confirm when we look at the project, because condition varies from one building to the next.
| Surface | Typical preparation | What to watch |
|---|---|---|
| Wood siding | Wash, scrape, sand, spot prime bare wood | Moisture and raw wood that soaks up paint |
| Trim and fascia | Scrape, patch, sand edges | Soft or rotted spots that paint cannot fix |
| Metal railings and doors | Remove loose coating, treat bare metal, prime | Rust coming back through the finish |
| Previously painted siding | Wash and check that the old coating is sound | Peeling or flaking that needs to come off first |
Timing
When is the right time to paint a house exterior?
Exterior paint goes on best over a dry, clean surface. Damp siding, a wet morning or rain in the forecast can all work against a good result. The paint manufacturer's label sets the temperature and drying limits for the product being used, and those limits decide which days are workable.
That is why exterior schedules depend on the weather. We plan the work around it and keep you informed when a day has to move.
If you are thinking about a project, it helps to ask early. Planning ahead gives room to choose colors, confirm the scope and fit the work into a stretch of suitable weather.
Planning
What affects the cost of an exterior painting project?
Every estimate starts from the same questions. Knowing them ahead of time makes the conversation faster:
- The size of the building and the number of stories
- The siding material and the condition of the current paint
- How much scraping, patching and repair the surfaces need
- Trim, doors, railings and other details beyond the main walls
- Access, including height, landscaping and tight spaces
- Whether the project is a repaint or a new color and finish
Photos help. Send a few of each side of the building with your request and the first conversation gets a lot more specific.
FAQ
Exterior painting questions
Do you power wash before painting?
Yes. Power washing is one of our services and a normal first step on exterior work, because paint needs a clean surface. You can also hire us for power washing on its own.
Do you spray or brush exterior surfaces?
Both. Spray applications are part of what we do, and brush and roller work is used where the surface or the detail calls for it. The method follows the surface.
Can you paint metal railings and doors?
Yes. Wood and metal coatings are part of our work. Metal is prepared for the coating going on it, and we talk through the details when we see the surface.
Do you paint commercial buildings?
Yes. JT Paint works on residential and commercial projects. See painting for contractors and property managers, or look at interior painting if the project includes the inside too.
Do you paint kitchen cabinets as well?
Yes. Take a look at cabinet painting and refinishing. Combining projects is a conversation to have when you request an estimate.
