Mastic sealing across Offham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.
Mastic sealing for commercial buildings in Offham
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Most enquiries involve repeated reactive repairs to the same buildings and brittle perimeter mastic across a building, on communal entrances and stairwells, window and door perimeters on blocks and external wall and movement 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.
Owners and agents with buildings around smaller places such as Offham tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
The 12-month guarantee covers our workmanship: 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.

What affects the price in Offham
Your fixed quote is built from the real scope. It allows for:
- How much existing material needs removing
- Travel to remote or island sites
- Quantities, in metres or numbers
- Working within restricted access windows
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Any dates the work must fit around
- The site address and postcode
- Photos of the joints, close up and from further back
- The product your specification calls for
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Questions about Offham
Is Offham too far out for you?
Not at all. Offham is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on a block within reach of Cooksbridge station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can you seal joints high up on a block?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Honest limits
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Glazing that needs replacing
- Materials that need asbestos testing before work
- Water coming in from the roof or rainwater goods
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly.
What we seal
- Window and door perimeters on blocks
