New build mastic in Heath End
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. We are often asked to deal with cracked sealant around new window and door frames and worktop and upstand sealant coming away, across show homes, skirting & floors and windows & doors.
Work in a small place like Heath End just needs the journey and access planning, and once on site, the job is the same as anywhere.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. Around Heath End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

DIY sealant or a professional job?
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 fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What affects the cost of new build mastic
For a quick quote, just ask. The main things that affect it are:
- The product the joint needs
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before any work starts.
What we need to know
There’s no need for technical detail. Just tell us:
- A few pictures by email, if you can
- How we’d reach the joints
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Heath End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive

Heath End questions
Is there a guarantee on new build mastic in Heath End?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Heath End within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we’ll give you a quote.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day before water reaches them.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
- Disputes or warranty claims with your builder
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
