Extension Plastering Services
Residential extensions often combine completely new construction with alterations to the original home. We can complete the new plasterwork while also addressing the junctions, repairs and finishing required where the two areas meet.

Existing Meets New
One of the most important parts of extension plastering is the transition between the original home and the new construction.
Existing walls and ceilings may contain older plaster, previous repairs or surfaces that are no longer perfectly straight or level, while the extension is generally built using new framing and plasterboard.
We assess these junctions and determine the most practical way to repair, join or replace affected areas so the plasterwork works properly with the new extension.

Plans & Details
Extensions can include more than standard walls and flat ceilings. Architectural plans may specify bulkheads, skylight openings, square-set junctions, stepped ceilings or other custom plaster details.
We can review drawings and plans before work begins to understand the required plastering details and identify areas that may need additional preparation.
This helps ensure the wall and ceiling work is completed in line with the overall design of the extension.
