Guilton New Build Mastic
New-build sealant joints in Guilton need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Sealant that never bonded to the surface
- Shower seals failing in the first year or two
- Internal frame sealant that has split
What we are called out for in Guilton
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Most people get in touch after spotting one of these:
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
Around Guilton, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Guilton
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation, because that is what rushed new-build sealant usually lacks. If you’re dealing with sealant work across a run of new homes and worktop and upstand sealant coming away, we can put it right.
For a small place like Guilton, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

How we quote for new build mastic
Your quote is based on your job. We look at:
- How easy the joints are to reach
- Any working-time requirements on site
- The type of sealant required
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Helping us quote
When you call or email, it’s useful to know:
- Photos by email, if that’s easy
- Roughly how big the job is
- Any access issues, like height or stairs
- What’s wrong with the joints now
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.
Your questions about new build mastic in Guilton
Do you work for landlords with property near Sandwich station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Guilton?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Can you do several jobs on one visit?
Yes. Just list everything you need.

The process
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours in a single home, depending on the size of the job. In a small place like Guilton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day before water reaches them.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Joints and finishes in Guilton homes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Sandwich station, it’s worth checking the sealant early, while snags are still fresh.
