About our remedial sealant in Naphill
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have photos when you ring 0345 464 0079 or drop us an email, and say how long ago it was last done. Common call-outs are for products that weren’t meant for the joint and a shower that leaks however often it’s resealed, across shrunken worktop sealant, mouldy bath & shower sealant and expansion joints.
Around Naphill, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
All our work comes with a 12-month guarantee, wherever you are in Buckinghamshire.

Your questions about remedial sealant in Naphill
Will you come out to Naphill?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Saunderton station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
How do I get a quote for remedial sealant in Naphill?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What the job involves on each surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Landlords and letting agents in Naphill can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Always have old sealant cut out, not covered
- Keep an eye on the ceiling below the bathroom
- Clean sealant with mild products only
- Deal with small splits early
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
Leave it or put it right?
Another bead over the top won’t fix a failed joint. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In a small place like Naphill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we will talk you through it.

When to call us in Naphill
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
The most common problems we see are:
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- A second bead peeling off the first
- Kitchen joints letting water behind the worktop
If you let a flat or house near Saunderton station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before you book

- What the quote includes, VAT included or not

Bathrooms and kitchens in Naphill
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as Church of St Botolph, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as Naphill and Walters Ash School, 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.
