Roydon New Build Mastic
We cover Roydon for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Second-fix sealing on new plots
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours in a single home, depending on how much there is to do. Somewhere as small as Roydon, 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.
- We make sure the joints are dry and prime them if needed.
- 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 if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

New build mastic in Roydon
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. We are often asked to deal with internal frame sealant that has split and gaps between new skirting and floors, on show homes, kitchens and bathrooms & en suites.
In a village or hamlet like Roydon, 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.
Your job is guaranteed for a year, as with all our work.

What new build mastic looks like in Roydon
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Roydon station, it’s worth checking the sealant early, while snags are still fresh. In and around Roydon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Bathrooms & en suites
- Plot handovers
- Kitchens
- Skirting & floors
- Windows & doors
- Show homes
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Put sealant faults on your snagging list early
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing so the sealant lasts.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Roydon: your questions answered
Do you work for landlords with property near Roydon station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can you do new build mastic in Roydon?
Yes, Roydon is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Who should fix failed sealant in a new build?
Start with the builder if you are in the snagging or warranty period. Once that’s done, or if they will not put it right, we will cut it out and reseal it.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Roydon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why choose Mr Mastic in Roydon
- You choose the colour before work begins
- Approved under the ARBOMaster scheme
- Full insurance on every job
- A 12-month guarantee on all work

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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
