Biggin New Build Mastic
Problem with your new-build sealant joints in Biggin? We cut out the old, prepare the joints and apply the right sealant.
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
Aftercare tips
To keep the joints looking good and working properly:
- Ventilate bathrooms well, especially in the first year
- Do not seal over failed sealant yourself
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
How we handle new build mastic in Biggin
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on kitchens, windows & doors and plot handovers, and people most often call us about joints pulling apart as timber shrinks and skirting joints opening in the first winter.
In a village or hamlet like Biggin, 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.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Common questions in Biggin
Is Biggin within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Biggin for new build mastic?
Yes, Biggin is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
How long does the job take?
That depends on how much there is to do, but as a guide it takes a few hours in a single home. We will tell you when we quote.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Biggin, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

What new build mastic looks like in Biggin
Biggin is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Biggin, as everywhere, new build mastic is only as good as the preparation behind it.

Do you need new build mastic in Biggin?
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Any of these means the joints need attention:
- Gaps behind new kitchen upstands
- Messy sealant that spoils new finishes
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
If you’ve bought a new home near Tilbury Town station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- How the colour is chosen
- How the surfaces are prepared before sealing
- How hidden problems are handled
- Whether all the old sealant comes out first
What else we do in Biggin
What happens if it’s left?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Around Biggin, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Biggin
- Sanitary silicone with an anti-fungal additive in wet areas

What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
