New build mastic for homes and businesses in Sunnymead
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. Common call-outs are for second-fix sealing on new plots and cracked caulk along new skirting, across plot handovers, skirting & floors and show homes.
In smaller places like Sunnymead, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Aftercare tips
So the new joints stay in good condition:
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.

What else we do in Sunnymead
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
If you manage several properties in or around Sunnymead, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes a few hours for most snagging lists, longer for a run of plots. For a job in Sunnymead, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job.
Related advice
What we are called out for in Sunnymead
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, and sealant that cannot keep up splits.
It’s worth asking for a quote if you see:
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Gaps opening as the house dries out and settles
- Plot mastic for developers ahead of handover
Around Sunnymead, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Is VAT in the price?
- Which sealant they’ll use, and why
- Whether you can choose the colour
- How long to leave it before use
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Joints and finishes in Sunnymead homes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Oxford Parkway station, the sealant around baths, showers and frames is worth checking in the first year or two.

- The product the joint needs

- The size of the job
- The old material and how stubborn it is
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
To make quoting easier, please include:
- The address or postcode of the job
- The rough size of the job
- If it’s domestic, commercial or a hotel

What sealant work can’t fix
New sealant can’t fix everything, and we will tell you before we start. It won’t solve:
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

Is the work guaranteed?

Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
