New Masonry

Masonry cleaning is a specialty at MGC. Over the years, we have worked very hard to develop work processes adapted to the different types of masonry, with the aim of cleaning them as well as possible without damaging their surface.

  • Our specialty: high-rise buildings and very large surfaces

Masonry Restoration

Teams that appreciate building heritage 

Quebec’s heritage abounds with monuments and masonry buildings that we have been proud to clean for many years. Our techniques do not damage the finish of the brick or stone (patina, baked-on layer) and comply with the most stringent environmental standards.

  • Historical buildings
  • Churches and monuments
  • Ancestral institutional buildings

Specialized Cleaning

There’s no stopping our cleaning experts: no matter the type of contaminants, we’ll have the right techniques to treat the masonry surface and dislodge the dirt.

  • Cleaning of salt and efflorescence deposits
  • Nebulization on stone surfaces with air pollution
  • Removal of bitumen and coating: caulk, glue, tar, etc. (by scraping or cold cleaning)
  • Hydro-detergent, use of specialized products to treat masonry surfaces according to their condition, composition and particularities
  • Use of poultices to remove contaminants in stones: rust, salt, etc.
