Common questions from Radnage clients
Can you match sealant colours for premises in Radnage?
Yes, we can normally get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.
Is Radnage too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is the old sealant taken out first?
Full removal is part of every quote. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What do you need from us to quote?
Send photos, drawings or a list of locations. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
Does commercial sealant work come with a guarantee?
The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.
Could the old sealant in an older building contain asbestos?
Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Radnage, the quickest start is to call the office on 01277 525 020 or email us with a list of addresses. Most enquiries involve gaps behind commercial kitchen worktops and sinks and leaks that seem to come through a sealant line, across window and door perimeters, external facade joints and kitchen worktops and splashbacks. Most enquiries from Radnage start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Common problems we fix in Radnage
A split down the middle of the bead tells a different story. Usually the movement was too much for the sealant chosen. The same product in the same joint tends to fail the same way.
These are often picked up first by site or facilities staff:
- Leaks that seem to come through a sealant line
- Expansion joints with the sealant torn out
- Sanitary sealant that has gone black and patchy
- Frame mastic that has hardened and come away from the wall
Trade counters and showrooms on estates such as Crownfield Industrial Estate, 1.8 miles to the north-east of Radnage, need neat joints where customers see them.

Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Radnage can sit alongside others in a wider programme across Buckinghamshire.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Whether the work must be split into stages
- How much existing material needs removing
- Travel to remote or island sites
- Quantities, in metres or numbers
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Clear photos of the problem areas
- Any dates the work must fit around
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email the details over.
Diagnose, treat, sign off
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building around Radnage, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- Send details through our quote form, or ask for a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Getting the site ready
- Agree which areas must stay open
- Send your site hours and access windows
- Warn occupants and staff about the work
Getting a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or send details through our quote form with what you know.

Working on commercial sites near Radnage
Rainfall across the South East, Radnage included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Two named trading, business or retail sites lie within about 3 miles of Radnage. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.
Shops and cafés around stations like Saunderton station, 1.6 miles east of Radnage, trade from early, so work is timed around them. A business with units at Crownfield Industrial Estate and Junction 5 Bates Industrial Estate needn’t use two contractors for its sealant.
Radnage is about 6 miles north-west of High Wycombe, in Buckinghamshire. We send applicators to Radnage for sealant joints. We work across 308 places in Buckinghamshire, from busy centres to rural villages. We also cover Reading, around 16 miles from Radnage.
Work on sealant joints is covered throughout HP14, whatever the building. Among the streets we cover are Bottom Road, Bower's Lane and Bennett End Road, and sites on any of them can send details for a fixed quote. If your building is just outside Radnage, we cover Bennett End (1 mile west), Bledlow Ridge (1 mile north-east), The City (1 mile south), Rout's Green (1 mile north) and Waterend (1 mile south-west). A short drive away, we cover Aylesbury (10 miles north), High Wycombe (6 miles south-east), Chesham (11 miles east), Marlow (8 miles south-east), Amersham (11 miles east) and Beaconsfield (10 miles south-east).
Near you in Radnage
We work on buildings around The Three Horseshoes Inn. For rail, the closest station is Saunderton station, roughly 1.6 miles east. Nearby you will also find Wycombe Hospital (5.5 miles south-east). Not far away are Yoesden and Bald Hill.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Cracking that needs a structural engineer to look at it
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think before you book.
Joints and surfaces we work on
- Washrooms and tea points
