Brick and Stone Work Built to Last
In Ronkonkoma, a lot of homeowners are out the door early and back late, and masonry problems tend to get noticed only when a brick falls out or a crack becomes obvious. By then, water has usually been working into the joints for a while, and every winter freeze has made the damage a little worse.
Promaster Maintenance Corp repairs, restores and builds brick and stone masonry for homes across Ronkonkoma, from the streets around the lake to the neighborhoods near the station. We also work in Lake Grove, Holbrook, Bohemia and Centereach.

Brick Repointing and Tuckpointing in Ronkonkoma, NY
Repointing is one of the best ways to protect your brick, and done right, it lasts for many years. Following the National Park Service's guidance, we use mortar that is softer than the brick and matched in color and texture to the original. When we repoint a Ronkonkoma home, we:
- Cut out the worn mortar to the correct depth
- Match the new mortar to the brick and existing joints
- Finish each joint so water runs off it
Too hard a mortar can crack the brick it is meant to protect, so the right mix is essential.
Chimney Masonry Repair in Ronkonkoma, NY
A chimney sees more weather than any other part of the house, and chimney damage is easy to miss from the ground. We repair:
- Spalled, cracked or loose chimney brick
- Chimney mortar joints that have worn open
- Chimney masonry that needs rebuilding
If you have noticed brick fragments on the roof or the ground below your chimney, it is worth having it checked.

Masonry Restoration for Older Brick and Stone

Your masonry ends up strong again without losing the look it had.
- Repairs damage while keeping the original materials
- Replaces spalled or broken brick and stone with close matches
- Restores sound, weathertight joints

Around Lake Ronkonkoma, some properties sit on gently sloping ground where a retaining wall holds back soil and creates level space. We repair retaining walls that are cracking, leaning or bulging and build new ones in stone and block.
Water building up behind a wall is a common reason it moves, so we look at the cause before deciding how to repair it.
Custom Masonry Construction for Your Home
For weekends at home, new masonry can turn a backyard into somewhere you actually want to spend time. We design and build:
- Outdoor kitchens
- Outdoor and indoor fireplaces
- Stone walls and retaining walls
- Custom porches
Each one is designed around your home and built to cope with Long Island weather.
How Much Does Masonry Repair Cost in Ronkonkoma, NY?
Every Ronkonkoma masonry job is priced after a free, no-obligation estimate at your home. The cost mainly depends on:
- The amount of masonry to repair, repoint or rebuild
- How deep the damage goes
- Matching brick, stone and mortar to your home
- Access to chimneys and higher walls
- The scope of any new construction
Warning Signs Your Masonry Needs Attention
Masonry damage is easy to overlook on a busy schedule, so keep an eye out for:
- Cracks in brick, stone or mortar joints
- Spalling, where brick faces flake or pop off
- Crumbling or missing mortar
- White, chalky staining called efflorescence
- Walls that lean, bulge or shift
Spalling and efflorescence usually mean moisture is moving through the masonry, so we find the source as well as fixing the damage.
