Wycombe Marsh questions
Do you cover smaller places like Wycombe Marsh?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near High Wycombe station?
Yes, we work for landlords and letting 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.
Can you seal where the floor meets the bath panel?
Yes. Floor edges in bathrooms and kitchens get wet at every clean, so a flexible silicone is the right choice.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Wycombe Marsh.
Can you use decorators’ caulk instead?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
About our floor joint sealing in Wycombe Marsh
Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on tiled floors, thresholds and wet room & bathroom floors, and the jobs we see most are perimeter joints in tiled floors filled with grout and threshold joints that have opened or worn.
For a small place like Wycombe Marsh, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, you get the same 12-month guarantee in Wycombe Marsh and across Buckinghamshire.

Why deal with it now?
Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Older cottages and farmhouses around Wycombe Marsh can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check the sealant is paintable before decorating
- Get cracks along tile grout lines looked at early
- Avoid caulk in bathrooms and kitchens
- Keep floor cleaning water to a minimum at the edges
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it until it’s ready.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on the length of joint, depending on the size of the job. For a village or hamlet like Wycombe Marsh, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints

Common problems we fix in Wycombe Marsh
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.
It’s worth asking for a quote if you see:
- Concrete floor joints that have broken down
- Grout cracking in a straight line across a floor
- Cracked caulk along skirting in bathrooms and kitchens
- Gaps opening between the floor and skirting
If you look after a church, hall or community building such as Church of St Anne, joints in its floors, skirtings and thresholds need resealing as they wear.
Before booking anyone
- What product goes in the joint
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
