Chalfont St Peter questions
Will you come out to Chalfont St Peter?
Yes. Chalfont St Peter is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Gerrards Cross station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is remedial work guaranteed?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

What affects the cost of remedial sealant
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- The number of rooms or windows
- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Roughly how big the job is
- Any previous sealing or DIY work
- A few photos by email, if you can
- Any access issues, like height or stairs
For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before any work starts.
Do you need remedial sealant in Chalfont St Peter?
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
People normally contact us after spotting something like this:
- Leaks that keep coming back after resealing
- Worktop sealant that has shrunk and split
- Smears and lumps from a botched reseal
- Dark patches showing through the sealant
Managing a site like Chalfont St Peter CofE Academy? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Questions to ask before booking
- Whether they seal over old material or remove it
- How the colour is chosen
- How much experience the applicator has
- When the joint can take water or movement
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Honest limits
A few problems are outside what sealant work can do:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A cracked shower tray or bath (that needs repair or replacing)
- Leaks from a shower valve, waste or pipework (a plumber’s job)

Remedial sealant around Chalfont St Peter
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. There are hotels and other places to stay in and around Chalfont St Peter. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For an older house near a landmark such as Parish Church of St Peter, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Gerrards Cross station? Then a joint that keeps failing is best fixed properly while the property is empty.

How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most joints, depending on how much old sealant has to come out from start to finish. A visit to Chalfont St Peter is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Clear the area around the work
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
