Our Mid to High-Rise Services Include:

Exterior Sealing

Exterior caulking and joint sealing for mid-rise and high-rise buildings, including curtain walls, window walls, precast and other façade joints. We work with property managers, condominium corporations and contractors to address water infiltration, air leakage and deteriorated sealants while coordinating access and work around occupied properties.

Firestopping

Firestopping for mid-rise and high-rise buildings, condominiums and other multi-storey properties. Our firestopping services include fire-rated joints, slab-edge systems, top-of-wall assemblies and demising walls, helping property managers, condominium corporations and contractors maintain critical fire separations and protect occupied buildings.

Seismic and Expansion Joints

Seismic and Expansion Joint Sealing

Specialized seismic and expansion joint sealing for mid-rise and high-rise buildings where structural movement requires flexible, durable joint systems. We work with property managers, condominium corporations and contractors to help protect wall, floor and building-envelope joints from water infiltration, weather exposure and premature deterioration.

Condo and Multi-Residential Re-Caulking

We help property managers, condo corporations and contractors coordinate full-building re-caulking with minimal disruption to residents. Our crews remove failed sealant and reseal windows, doors, vents and exterior façade joints on occupied mid-rise and high-rise buildings.

Their estimator Rob was very thorough and a pleasure to deal with.  The father and son team were conscientious and did a wonderful job.  We would definitely recommend them.

 Trustindex verifies that the original source of the review is Google. Just had all my windows and doors recaulked on my 24-year old house. Armando and his assistant did an amazing job. They not only removed all the old caulking but applied new caulking on all my windows and doors. They also removed all the rust that had built up around some of my windows and repainted with rust-proof paint. They were professional, quick and I appreciated how they were careful with moving some of my planters. They did a great job cleaning up as well. Very friendly. I highly recommend them.
