About our construction mastic in Sandhurst
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal sealing often fills those days. We work on floor and skirting junctions, window and door perimeters and internal decorators’ caulk, and what we are called in for most is early adhesion failures on new external joints and a mastic package split between trades with no clear owner. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Sandhurst, preparation and product choice get the time they need.
Construction in a town such as Sandhurst is often smaller schemes: a few new flats, a school extension, a refurbished unit. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
Our workmanship is guaranteed for 12 months, in Sandhurst as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Joints damaged after sign-off by following trades
- Approving fire stopping as compliant
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

Contractors’ notes for Sandhurst
Sandhurst is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. A 2-mile radius around Sandhurst takes in a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
On a healthcare site such as Broadmoor Hospital, which lies north of Sandhurst, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Recladding or extending a unit at a site like The Meadows Business Park, 1.2 miles south of Sandhurst, brings panel joints and frame perimeters into the programme. School extensions, at buildings such as Sandhurst School, usually run to the summer holidays, mastic included.

What happens if it’s left?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. We will say so if a frame itself is the problem. In Sandhurst, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.

When to bring in a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Common questions from Sandhurst clients
Can you work on a hospital site such as Broadmoor Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you keep pace with our programme in Sandhurst?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Do you cover Sandhurst?
Yes. We take on work across Sandhurst.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Most work in Sandhurst is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Let us know about inductions and permits
- Make sure the joints can be reached
- Arrange parking or a loading space

Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Ask for joint and product checks before the package is urgent
- Brief following trades on areas that have been sealed
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
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 so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
