New-build mastic & snagging in Coryton, Thurrock
Professional new build mastic in and around Coryton, with every bit of old sealant taken out first.
- Internal frame sealant that has split
- Sealant that never bonded to the surface
- Worktop and upstand sealant coming away
New build mastic in Coryton, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. If you’re dealing with beads laid onto grit and dust from the build and worktop and upstand sealant coming away, we can help, whatever the surface.
Around Coryton, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home and we leave things clean and tidy. In a small place like Coryton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- 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.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints

Aftercare tips
To keep the joints looking good and working properly:
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Use the extractor fan every time you shower
- Clean sealant with mild detergent, not abrasives
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Common problems we fix in Coryton
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
These are the problems we are asked about most:
- New-build shower sealant that has already split
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
In and around Coryton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- Are they insured?
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
Coryton: your questions answered
Is Coryton within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Benfleet station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the number of plots, including the preparation. We will confirm how long when we quote.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we will do.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we’re happy to quote.
DIY sealant or a professional job?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What sealant work cannot fix
It helps to know what we can’t do:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
- Skirting & floors
- Bathrooms & en suites
- Windows & doors
- Kitchens
- Show homes
- Plot handovers
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
What affects the cost of new build mastic
We do not publish a price list, because jobs vary so much. The quote depends on:
- How much there is to do
- How easy the joints are to reach
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Helping us quote
To help us quote quickly, please include:
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The type of property
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or drop us an email.
