Brick and Stone Work Built to Last
Brentwood's streets are lined with mid-century ranches, capes and split levels, and many of them have a brick chimney, a brick front or brick planters that are now decades old. That kind of masonry was built to last, but by this age the mortar has usually done its job and needs attention.
Promaster Maintenance Corp repairs, restores and builds brick and stone masonry for Brentwood homeowners, from a handful of loose bricks to a chimney rebuild. We also work in nearby Central Islip, Edgewood, Deer Park and North Bay Shore.

Masonry Repair for Brick, Stone and Block in Brentwood
Once water gets into a crack, each freeze pushes it wider, so a minor repair today can prevent a major one later. We offer:
- Brick repair and replacement on fronts, chimneys and walls
- Mortar repair where joints are loose or missing
- Crack repair in walls and structures
- Chimney masonry repair
- Structural repairs to damaged masonry
We match the new brick and stone to your existing masonry so the repair is hard to spot.
Brick Repointing and Tuckpointing in Brentwood, NY
On a decades-old Brentwood home, repointing is often the single most useful masonry job you can do. We follow the National Park Service's preservation guidance, which calls for mortar that is softer than the brick and matches it in color and texture. When we repoint, we:
- Remove the old, failing mortar to the proper depth
- Match the new mortar to your existing brick and joints
- Tool the joints so they shed water
A mortar that is harder than your brick can crack the brick around it, so we always match the mix to the masonry.
Chimney Masonry Repair in Brentwood, NY
Brick chimneys on Brentwood's older homes take a beating from wind, rain and decades of freeze and thaw. We repair:
- Open or crumbling mortar joints
- Cracked or spalled chimney brick
- Leaning or failing chimney masonry that needs rebuilding
Dealing with the joints early is usually all it takes to keep a chimney sound for years to come.

Masonry Restoration for Older Brick and Stone
Restoring the original masonry on a mid-century home often costs less than replacing it and keeps the house looking right. Promaster Maintenance Corp evaluates the masonry in detail and then plans work that:
You end up with masonry that is solid again and still in keeping with the house.
- Saves original brick and stone where it is still sound
- Restores tight, weatherproof joints
- Swaps spalled or broken units for close matches

In Brentwood, retaining walls tend to be smaller garden walls, raised beds and planters, and they still need to be built properly to stay straight. We repair walls that have cracked, leaned or bulged and build new walls in stone and block.
If a wall has moved, we look at the cause, including water collecting behind it, before deciding how to repair it.
Custom Masonry Construction for Your Home
We also design and build new masonry to give a Brentwood property more character and more usable space:
- Custom porches
- Outdoor kitchens
- Indoor and outdoor fireplaces
- Stone walls
Every feature is built around your home and the way your household uses it.
How Much Does Masonry Repair Cost in Brentwood, NY?
The cost of masonry work in Brentwood depends on what we find, so we give every homeowner a free, no-obligation estimate on site. The main factors are:
- How much masonry needs repair, repointing or rebuilding
- Whether the damage is surface-level or structural
- Matching brick, stone and mortar to your home
- Reaching the work, for example on a chimney
- The size of any new construction
Warning Signs Your Masonry Needs Attention
On older Brentwood homes, these are the signs that masonry needs looking at:
- Mortar that is crumbling or missing between bricks
- Cracks in brick, stone or mortar
- White, chalky marks on the brick, called efflorescence
- Spalling, where brick faces flake or break away
- Walls or chimneys that lean, bulge or shift
When we see efflorescence or spalling, we look for the moisture causing it as well as repairing the damage.
