Mastic sealing for Wexham Street sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Doing it in-house
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.
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 normally costs more in the end than doing them right.
Mastic sealing for commercial buildings in Wexham Street
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. Site teams most often ask us about the same joint failures repeated across a portfolio and brittle perimeter mastic across a building, on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Wexham Street it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Which sealant the job calls for
- The size and state of each joint
- Induction, permit and paperwork requirements
- How much existing material needs removing
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- Asbestos survey details if the building is older
- When you need the work done
- Anything awkward about access or site hours
- The type of building and who uses it
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email the details over to discuss it first.

What else we do in Wexham Street
Why act early in Wexham Street
Failed perimeter mastic lets cold air in around frames and the windows normally get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Around Wexham Street, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What you get with us
- Colour options checked against the specified product
- One phone line for London, the South East and Scotland
- 12 months’ guarantee on every job
- Colours chosen to suit frames, cladding or finishes where possible

Wexham Street: questions and answers
Is The Business Village, near Wexham Street, within your area?
Yes, sites like The Business Village are within our area, along with the rest of Wexham Street. A few photos and the unit address let us price the work.
Is Wexham Street off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Will residents or tenants be disturbed?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
