What siding Installation and Repair covers
Siding is a rain screen rather than a waterproof layer. Water gets behind it, and the weather barrier and flashings underneath are what actually keep the wall dry. Most siding failures are failures of what is behind the boards rather than the boards themselves.

New and repaired siding, with the weather barrier behind it treated as the part that matters.
Waystar carries out this work on residential and commercial property in Brooklyn and across New York City. Every project starts with a look at the building, and the scope, the materials and the figures are written down before anything begins.
When might you need it?
These are the signs owners usually notice first.
- Boards cracked, split or blown loose in an area
- Damp inside on a wall that is sided outside
- Siding that has faded or chalked unevenly
- Gaps opening at corners, around windows or at trim
- Signs of rot in the sheathing behind the siding
What the work involves
- Survey including a check behind the siding where possible
- Failed boards and any rotten sheathing removed
- Weather barrier installed or repaired and lapped correctly
- Flashings formed at openings, corners and terminations
- Siding installed with the correct fixing and expansion gaps
- Trim, corners and penetrations sealed and finished
How the process works
Look behind the boards
Removing a section shows the sheathing and barrier condition, which decides the real scope.
Repair the barrier
Weather barrier and flashings are corrected before any new siding goes up.
Flash the openings
Windows, doors, corners and penetrations are detailed to shed water outward.
Install and finish
Boards fixed with proper expansion allowance, then trim and sealing.
What you get
- The barrier behind the siding put right, not just the visible boards
- Flashings at the openings where water most often gets in
- Fixings that allow movement instead of restraining it
What affects the scope
- How much sheathing turns out to be damaged
- Whether the existing weather barrier can be retained
- Siding material and how it handles movement
- Number of openings, corners and penetrations to detail
This is a preliminary planning range, not a quote. A property visit is required before any price is confirmed.
Frequently asked questions
Can new siding go over the old?
Sometimes, but it hides the barrier and any rot behind it. We will tell you when it is reasonable and when it is storing up a problem.
Why is my wall damp when the siding looks fine?
Because siding is not the waterproof layer. The barrier and flashings behind it are, and that is usually where the failure is.
Will you match my existing siding?
Where the profile is still available, closely. Where it is not, we will show you the nearest option before ordering.
