Little Wittenham New Build Mastic
Professional new build mastic in and around Little Wittenham, with every bit of old sealant taken out first and a 12-month guarantee.
- Cracked sealant around new window and door frames
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
New build mastic in Little Wittenham, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you are dealing with untidy sealant flagged on a snagging list and sealant that never bonded to the surface, we can help, on kitchens, windows & doors and show homes alike.
Around Little Wittenham, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

New homes and floors in Little Wittenham

If you’ve bought a new home near Appleford station, the sealant around baths, showers and frames is worth checking in the first year or two.

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Little Wittenham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

FAQs for Little Wittenham
Is Little Wittenham within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Appleford station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.
When is the best time to reseal in a new build?
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.
The process
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Somewhere like Little Wittenham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

Related advice
Landlords, agents and businesses in Little Wittenham
Landlords and agents in Little Wittenham can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Keeping the joints in good condition
So the new joints stay in good condition:
- Follow the cure time we give you
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
- Get a leaking seal dealt with straight away
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.

What we are called out for in Little Wittenham
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
It’s worth asking for a quote if you see:
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
Around Little Wittenham, as everywhere, new build mastic is only as good as the preparation behind it.

- When the joint can take water or movement
- How hidden problems are handled
- What preparation is included
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
