Construction mastic in Somerton
Since 2005 we have worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Somerton, send drawings and the specification through our quote form. Most enquiries involve existing joints on a refurb that need cutting out and resealing and sanitary sealant damaged by following trades, across internal decorators’ caulk, cladding and panel joints and window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Somerton is the same: the right product in a properly prepared joint.
Around smaller places like Somerton, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we’re called out for in Somerton
A new building moves while it dries and settles. Materials lose construction moisture and shrink and internal caulk in a moving joint is normally the first to crack. Choosing the right product for each joint reduces that.
Most enquiries start with one or more of the following:
- Old sealant on a refurbishment that needs stripping before new work
- Snag items on joints that need redoing before handover
- New external sealant already peeling away
- Inconsistent sealant finishes from plot to plot
When units on a site such as Hatch End Old Industrial Estate, 2 miles to the south-west of Somerton, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Questions about Somerton

Yes. Estates, retail parks and business parks around Somerton, Hatch End Old Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Can the mastic package for our job in Somerton follow the site programme?
Yes, we work to the programme and the sequence the site sets. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Are you fully insured?

Yes. Somerton is in our area. For a quote, call the office on 01277 525 020 or email drawings and photos.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects, especially externally. Where an alternative is genuinely suitable, we’ll say so. Converted and older buildings near places like Somerton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Facades, frames and programmes in Somerton
Central London is about 60 miles from Somerton. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Somerton included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

What else we do in Somerton
What affects the price in Somerton
The price varies from site to site. Expect it to depend on:
- Which sealant the job calls for
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Whether the building will be occupied during the work
- Access details, including height
- Photos of the joints, close up and from further back
- Specification clauses that apply
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send photos by email.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Frame gaps too wide for sealant, which the installer needs to correct
- Approving fire stopping as compliant
- Faulty frames rather than failed sealant
If you are not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer before you book.

When to bring in a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
