Hawridge New Build Mastic
Our applicators work in Hawridge on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
How we handle new build mastic in Hawridge
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you’re dealing with sealant applied over dusty or wet surfaces and internal frame sealant that has split, we can help, whatever the surface.
In a village or hamlet like Hawridge, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Your job is guaranteed for a year, as with all our work.

Why deal with it now?
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, ring 0345 464 0079 or send us an email with photos and we will give you a straight answer. Around Hawridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before any work starts.

Is Hawridge in your area for new build mastic?
Yes, Hawridge is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
How do I get a quote for new build mastic in Hawridge?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and tell us what needs doing and where.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Should I go to my builder first?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our one-year guarantee.
Where do you work from?
We work from Crawley. Our applicators cover Hawridge, along with the rest of our area.
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

Quotes for new build mastic in Hawridge
We don’t publish a price list, because jobs vary so much. What we look at:
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- How easy the joints are to reach
- How many rooms, windows or areas are involved
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
Helping us quote
Photos help, but a description is a good start. Please mention:
- A few pictures by email, if you can
- What’s wrong with the joints now
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Looking after it afterwards
To keep the joints looking good and working properly:
- Get a leaking seal dealt with right away
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. Somewhere like Hawridge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- 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.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Common problems we fix in Hawridge
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
Common reasons people contact us include:
- Shower seals failing in the first year or two
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Internal frame sealant that has split
If you’ve bought a new home near Berkhamsted station, the sealant around baths, showers and frames is worth checking in the first year or two.
