Need construction mastic in Radnage?
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What we are called out for in Radnage
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
It’s worth sending us details if you spot any of the following:
- Bath and shower joints scraped during the final clean
- New external sealant already peeling away
- Frame perimeters left unsealed or poorly sealed
- Internal caulk splitting as the building dries out
Older buildings in the area around Radnage, such as West Wycombe Park House, 3.2 miles south-east of Radnage, need care when sealed: the product has to suit soft or historic materials.

What else we do in Radnage
Building and refurbishing in Radnage
Radnage is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Radnage is about 35 miles from central London. 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.
On a healthcare site such as Wycombe Hospital, 5.5 miles south-east of Radnage, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. School extensions, at buildings such as Radnage Church of England Primary School, normally run to the summer holidays, mastic included.
Radnage is about 6 miles north-west of High Wycombe, in Buckinghamshire. Commercial clients in Radnage can call on us for mastic packages, as part of our coverage of Buckinghamshire.

Your questions answered
Do you cover business parks and estates near Radnage, such as Crownfield Industrial Estate?
Yes. Our area takes in Radnage and its surroundings, with estates and business parks such as Crownfield Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is Radnage off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
How do I request a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team and updated as the programme moves.
What guarantee comes with a mastic package?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we’ve finished isn’t covered.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Commercial clients in Radnage
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Joints damaged after sign-off by following trades
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Approving fire stopping as compliant
If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.

Cost factors for mastic packages
Each job is priced on its own details. The main factors are:
- Joint width, depth and condition
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- The type of building and who uses it
- Whether an asbestos survey exists
- Any specification or named product
- Drawings or a marked-up plan, if available
