About our construction mastic in Offham
The specification and the programme set the job. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. Site teams most often ask us about snag items on joints that need redoing before handover and frame perimeters left unsealed or poorly sealed, across cladding and panel joints, brick and block movement joints and sanitary and kitchen joints. Most enquiries from Offham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Conversions of older rural buildings near smaller places such as Offham bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Different surfaces, different methods
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area.
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Approving fire stopping as compliant
- Glazing units that are cracked or misted
- Joints damaged after sign-off by following trades
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.

Construction mastic in Offham: the local picture
Offham lies roughly 25 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. A 2-mile radius around Offham takes in several hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
For a contractor at a hotel such as Bear Hotel, which lies east of Offham, the mastic often has to be finished before a reopening date. Historic houses such as Old Soar Manor (3.1 miles south-west of Offham) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

What we are called out for in Offham
A new building moves while it dries and settles. Materials lose construction moisture and shrink and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
Most enquiries start with one or more of the following:
- Inconsistent sealant finishes from plot to plot
- Oversized or tapered gaps around new frames
- Internal caulk splitting as the building dries out
- Snag items on joints that need redoing before handover
New units and refits on sites such as Kings Hill Business Park, 1.5 miles to the south-east of Offham, need their panel and perimeter joints sealed to the specification.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- Will RAMS and insurance details be available?
- How long is the guarantee, and what does it include?
- Their public liability cover
