New Build Mastic in Bledlow
Problem with your new-build sealant joints in Bledlow? We cut out the old, prepare the joints and apply the right sealant.
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
Leave it or put it right?
The builder is normally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In a small place like Bledlow, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
Why us?
- Every job guaranteed for a year
- White, clear, grey or coloured to suit, where the product allows
- We are fully insured
- More than 20 years in sealant work
New build mastic in Bledlow, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on kitchens, show homes and windows & doors, and common reasons people get in touch are new-build shower sealant that has already split and worktop and upstand sealant coming away.
Older homes in small places like Bledlow often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job.

Landlord and commercial work in Bledlow
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours in a single home. Somewhere as small as Bledlow, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Different surfaces, different methods
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What sealant work cannot fix
In fairness, some problems need a different trade:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

Bledlow questions
Is Bledlow within the area you cover?
Yes, Bledlow is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Princes Risborough station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Bledlow, along with the rest of our area.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you work through snagging lists?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
