New build mastic in Throwley Forstal
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We’re often asked to deal with second-fix sealing on new plots and skirting joints opening in the first winter, on windows & doors, plot handovers and bathrooms & en suites.
In a village or hamlet like Throwley Forstal, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Our work is backed for twelve months, in Throwley Forstal and everywhere else we cover.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. For a village or hamlet like Throwley Forstal, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules

Related advice
Why act early in Throwley Forstal
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Around Throwley Forstal, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we will talk you through it.

How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
- The old material and how stubborn it is
- The number and length of the joints
- Whether the work is at height
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What we need to know
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- The address or postcode of the job
- Any previous sealing or DIY work
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
When something else is needed
Sealant is not the answer to every problem, and we will tell you before we start. It will not solve:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.
