How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.
How we handle new build mastic in Pegwell
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you are dealing with joints pulling apart as timber shrinks and untidy sealant flagged on a snagging list, we can help.
Around Pegwell, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All our work comes with our 12-month guarantee.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant

Landlords, agents and businesses in Pegwell
We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Avoid running a DIY bead over the old one
- Open a window or run the fan after bathing
- Look at the sealant regularly in the first couple of years
- Avoid scourers and strong chemicals on sealant
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Joints and finishes in Pegwell homes
Pegwell 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. 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.
In and around Pegwell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Ramsgate station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in Pegwell
Your questions about new build mastic in Pegwell
Will you come out to Pegwell?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do new build mastic in Pegwell?
Yes, Pegwell is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Why does sealant fail so quickly in new builds?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere as small as Pegwell, access is often the only tricky part. 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.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Mention any tricky access
How to get a quote

What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Pegwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
