About our construction mastic in Westborough
Mastic tends to be one of the final packages before handover. We work as a mastic subcontractor to main contractors and developers with projects in Westborough, sealing plot by plot or floor by floor as areas are released. If you have failed sealant in an existing building being refurbished and caulk cracking where joints are moving more than expected, we can help. Whoever orders the work in Westborough, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Conversions around smaller places like Westborough often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Keeping the joints sound
Regular inspection catches problems early. In particular:
- Record the products used in the O&M file
- Allow flexibility for external sealing in damp or cold weather
- Ask cleaners to use soft cloths around fresh sealant
- Check frame gaps are within the sealant’s range before sealing
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.
Contractors’ notes for Westborough
There are a good number of hotels within about 2 miles of Westborough. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Central London is about 28 miles from Westborough. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
Units on estates such as Guildford Industrial Estate (to the east of Westborough) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Hotel extensions and refits, at places such as Asperion Hotel, 0.9 miles south-east of Westborough, usually run between busy periods, so the sealing is squeezed into short windows.

FAQs: Westborough
Is Westborough too small for you to travel to?
No. Places such as Westborough are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Can you work around term dates at a campus such as University of Surrey?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you take on mastic snagging only?
Yes. We clear snags by redoing joints rather than patching them.
Do you offer coloured sealant?
That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you use the sealant named in the specification?
We follow the specified sealant, and we’ll raise it if something in it doesn’t suit the joint. Product standards such as BS EN 15651 are often named in specifications.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Rework caused by others damaging completed areas
- Faulty frames rather than failed sealant
- Approving fire stopping as compliant
If you are not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Surfaces we seal
- Brick and block movement joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
What we’re called out for in Westborough
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Any of the following is a good reason to get the joints checked over:
- Oversized or tapered gaps around new frames
- Mastic snags holding up handover
- External joints sealed in damp or cold conditions that are now failing
- Frame perimeters left unsealed or poorly sealed
On a campus such as University of Surrey (under half a mile north of Westborough), new teaching buildings and residences are usually built and refurbished around the academic year.

- The named product and why it was chosen
- How they handle RAMS and site documents
- Health and safety accreditation such as CHAS

Advice
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Phasing around occupants
- The total length or number of joints
- Site requirements such as inductions and permits
- Location, for remote and island sites
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- Where the site is, with the postcode
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
