Cockpole Green New Build Mastic
We cover Cockpole Green for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
- Joints pulling apart as timber shrinks
New build mastic in Cockpole Green, done properly
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. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on plot handovers, windows & doors and kitchens, and people most often call us about cracked sealant around new window and door frames and worktop and upstand sealant coming away.
Work in a small place like Cockpole Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
All our work comes with our one-year guarantee.

How we quote for new build mastic
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- The number and length of the joints
- How many areas need sealing
- The type of sealant required
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- Where the property is
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.

Aftercare tips
To keep the joints looking good and working properly:
- Don’t seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. 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 in a busy bathroom.

Other services in Cockpole Green
Do you need new build mastic in Cockpole Green?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
These are the problems we are asked about most:
- Sealant applied over dusty or wet surfaces
- New-build shower sealant that has already split
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
In and around Cockpole Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
How it works
Before we leave, we go over the finished joints with you. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a village or hamlet like Cockpole Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Older cottages and farmhouses around Cockpole Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Common questions in Cockpole Green
Will you come out to Cockpole Green?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Cockpole Green in your area for new build mastic?
Yes. We work across London and the South East, and Cockpole Green is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
