How we handle new build mastic in Hazlemere
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on show homes, windows & doors and kitchens, and people most often call us about gaps behind new kitchen upstands and new-build shower sealant that has already split.
In and around Hazlemere, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
Big or small, you get the same one-year guarantee.

The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Parking around Hazlemere is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

Advice
What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- The type of sealant required
- Any mould that needs treating
- How many areas need sealing
- Whether the work is at height
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.

Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Homes in smaller places like Hazlemere can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

When to call us in Hazlemere
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
If you can see any of these, it’s time to have the joints looked at:
- Sealant applied over dusty or wet surfaces
- Untidy sealant flagged on a snagging list
- Joints pulling apart as timber shrinks
- Plot mastic for developers ahead of handover
If you’ve bought a new home near High Wycombe station, the sealant around baths, showers and frames is worth checking in the first year or two.

Your questions about new build mastic in Hazlemere
I let a flat near High Wycombe station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Hazlemere for new build mastic?
Yes, Hazlemere is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish before we begin.
How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We’ll confirm how long when we quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
