Construction mastic in Stratfield Mortimer
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers with projects in Stratfield Mortimer, sealing plot by plot or floor by floor as areas are released. We work on floor and skirting junctions, window and door perimeters and brick and block movement joints, and what we are called in for most is cracks opening in caulked internal joints and early adhesion failures on new external joints. Looking for mastic applicators who cover Stratfield Mortimer? We have been sealing commercial buildings since 2005.
Sites around smaller places like Stratfield Mortimer can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Frame gaps too wide for sealant, which the installer needs to correct
- Rework caused by others damaging completed areas
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Working within restricted access windows
- Which sealant the job calls for
- Site requirements such as inductions and permits
- Travel to remote or island sites
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
- Access details, including height
- Where the site is, with the postcode
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Common problems we fix in Stratfield Mortimer
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.
It’s worth sending us details if you spot any of the following:
- Old sealant on a refurbishment that needs stripping before new work
- Internal caulk splitting as the building dries out
- A long mastic snag list close to completion
- Oversized or tapered gaps around new frames
Older buildings in the area around Stratfield Mortimer, such as Stratfield Saye House (2.7 miles south-east of Stratfield Mortimer), need care when sealed: the product has to suit soft or historic materials.
What your quote should include
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents

Building and refurbishing in Stratfield Mortimer
Stratfield Mortimer sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. At about 42 miles from central London, Stratfield Mortimer is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
When a school such as Mortimer St Mary's C.E. Junior School is extended or refurbished, the mastic package is often squeezed into the holidays.

Aftercare for building managers
Regular inspection catches problems early. In particular:
- Keep product details for future maintenance
- Keep scrapers and abrasive pads off new beads
- Ask installers to correct oversized gaps first
- Don’t schedule sealing before decorators and flooring are done
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
