How NSJ approaches every project

Every job starts with assessment, not assumption. The chain we follow:

The client was seeing — the symptom the owner or manager noticed
The risk — what could worsen if the visible fault was treated as a surface issue only
What we found — the actual defect, route of water or air entry, or fabric issue
What we did — the proportionate repair method and compatible materials
What this protected — the building fabric, opening or client from repeat repair costs

Examples of work we regularly carry out

Typical projects include:

Cement mortar repointing on exposed brick elevations
Lime mortar repointing on older stone properties
External sealant replacement around window frames
Internal bathroom and kitchen resealing
Window and door gasket replacement
Patio joint repair
Masonry repairs to damaged brick or stone

Each of these services addresses common building envelope defects.

Why correct diagnosis matters

Many building defects appear similar at first glance.

For example, water appearing around a window may be caused by:

failed external sealant
degraded window gaskets
deteriorating mortar joints

Identifying the correct source of failure ensures the repair is effective and long-lasting.
