New-build mastic & snagging in Goodnestone, Kent
Our applicators work in Goodnestone on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Cracked sealant around new window and door frames
What we do, step by step
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. Somewhere as small as Goodnestone, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

New build mastic in Goodnestone, done properly
Across Goodnestone, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you’re dealing with internal frame sealant that has split and sealant applied over dusty or wet surfaces, we can help.
Older homes in small places like Goodnestone often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Cracked trays, tiles or worktops
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the quote in Goodnestone
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- Whether the work is at height
- Which sealant suits the joint
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
