When Should We Have Our Building Envelope Maintained?

Due to the damp climate which haunts Britain for the majority of the months of spring, autumn and winter, summer presents a rare period of sustained dry patches. This makes it the perfect time to embark on required maintenance work to a building’s envelope.

This is because a building’s envelope, which consists of the foundation, walls, windows, doors and roof, is specifically designed to protect a building from external factors such as temperature, air and most importantly moisture. In order to be truly effective, building envelope maintenance work should be undertaken in a dry environment. Otherwise you run the risk of trapping moisture from damp conditions within your building and limiting the effect of the maintenance work.

It is important to ensure that a building’s envelope is correctly maintained for a number of key reasons. Namely, to ensure that the building’s structural integrity is preserved, to retain the value of the property and to ensure that it is adequately waterproofed. In order to ensure that the final factor is achieved to the optimum standard it makes sense to do it during the drier summer months, to provide ample protection for the wet months of Spring, Autumn and Winter.

CJ Paint Spraying are perfectly placed to undertake maintenance work on your building envelope. Our team of dedicated and experienced professionals and engineers have undertaken highly specialised maintenance projects to the envelopes of a diverse range of structures. In order to provide the optimum service we work closely with building design closure and envelope consultants, in order to plan and implement the best solution for each specific situation. This approach also ensures that the maintenance work we undertake provides durability.

Unlike other contractors in this field, all of our work is undertaken in reference to the design plan and specifications of the building, as developed by an engineer and/or architect. Prior to the commencement of work we evaluate the scope of the project, provide a detailed outline of estimated costs and outline the project’s timescales, meaning no unexpected surprises or costs for you.

The scope of our building envelope maintenance work includes:

  • Structural steel repair and replacement
  • Exterior and interior finish repairs
  • Siding replacement
  • Sealant and waterproofing coatings and membranes
  • Window repair and door repair and replacement
  • Weather stripping
  • Leak investigation services
  • Inspection and exploratory testing services
