What affects the quote in Radley
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Any working-time requirements on site
- Whether the work is at height
- Mould in or behind the old joints
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
Photos by email are helpful but not essential. Please mention:

- What’s wrong with the joints now
- How we’d reach the joints

About our new build mastic in Radley
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Typical jobs include smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames, across kitchens, windows & doors and plot handovers.
For a small place like Radley, the journey and access are planned in advance, and the work itself is the same as on any site.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing so the sealant lasts.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
What new build mastic looks like in Radley
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Radley station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Radley, as everywhere, new build mastic is only as good as the preparation behind it.

What sealant work cannot fix
New sealant can’t fix everything, and we’ll tell you before any work starts. It won’t solve:
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
- Cracked trays, tiles or worktops
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours in a single home. Somewhere like Radley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules

Advice
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep photos and emails about snagging items
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Common questions in Radley
I let a flat near Radley station. Can you help?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Radley?
Yes, Radley is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I wait before resealing?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Who should fix failed sealant in a new build?
Your builder, if you’re still in their snagging or warranty period. If that doesn’t work out, we’re happy to quote.
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In a small place like Radley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.
