New-build mastic & snagging in Drayton, Portsmouth
New build mastic in Drayton from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Internal frame sealant that has split
- Shower seals failing in the first year or two
- Cracked caulk along new skirting
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Follow the cure time we give you
- Wipe joints with warm soapy water
- Do not wait for the house to settle if water is getting through
- Photograph failed sealant before it’s redone
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
New build mastic in Drayton, done properly
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you’re dealing with plot mastic for developers ahead of handover and beads laid onto grit and dust from the build, we can help, whatever the surface.
In and around Drayton, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

- Which sealant suits the joint

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
When you call or email, it’s useful to know:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Roughly how big the job is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Common problems we fix in Drayton
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
People usually contact us when they notice something like this:
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
For new homes near Cosham station, it’s worth checking the sealant early, while snags are still fresh.
Before booking anyone
- What insurance they hold
- What happens if they find a problem under the old sealant
- Who turns up on the day
- When the joint can take water or movement
How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for most snagging lists, longer for a run of plots. A visit to Drayton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work

What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.
Landlords, agents and businesses in Drayton
Landlords and agents in Drayton can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for property managers and facilities teams in Drayton and across Portsmouth. We can quote a run of properties together, and we’re fully insured.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

New build mastic around Drayton
Drayton is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
