About our construction mastic in Lathbury
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. Most enquiries involve perimeter gaps outside the sealant’s range and external joints sealed in damp or cold conditions that are now failing, on internal decorators’ caulk, cladding and panel joints and brick and block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lathbury it comes down to the same thing: the right product in a properly prepared joint.
Sites around smaller places like Lathbury can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Frame gaps too wide for sealant, which the installer needs to correct
- Faulty frames rather than failed sealant
- Deciding which fire-stopping product a penetration needs
If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal
- Floor and skirting junctions
- Internal decorators’ caulk

Building and refurbishing in Lathbury
Lathbury sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Several hotels sit less than 2 miles from Lathbury. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When a school such as Cedars Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. University estates such as Cranfield University (to the south-east of Lathbury) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Lathbury: questions and answers
Is Lathbury off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Could you schedule work at a campus like Cranfield University for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
What does a mastic package typically include?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens in one fixed quote.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

What else we do in Lathbury
Why act early in Lathbury
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility. Halls, stores and units around places like Lathbury may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Common problems we fix in Lathbury
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We use what’s specified, and any substitute goes to you for acceptance.
What tends to prompt an enquiry:
- Existing joints on a refurb that need cutting out and resealing
- Snag items on joints that need redoing before handover
- External joints sealed in damp or cold conditions that are now failing
- Frame perimeters left unsealed or poorly sealed
Extensions at sites like Blakelands Hospital, 1.9 miles to the south-west of Lathbury, normally sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Proof of insurance
- Is the sealant right for the movement and the substrate?
- How joint depth will be controlled
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Ask installers to correct oversized gaps first
- Keep scrapers and abrasive pads off new beads
- Record the products used in the O&M file
- Put any product change through the designer first
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. Tell us what records you need and we’ll confirm with the quote.
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, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
