New build mastic for homes and businesses in North Moreton
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on bathrooms & en suites, skirting & floors and kitchens, and the jobs we see most are sealant applied over dusty or wet surfaces and joints pulling apart as timber shrinks.
Around North Moreton, 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 will put it right.

Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like North Moreton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Common questions in North Moreton
Do you work for landlords with property near Didcot Parkway station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Can you do new build mastic in North Moreton?
Yes. Our work covers London and the South East, and North Moreton is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Where is Mr Mastic based?
We work from Crawley. We cover North Moreton and the rest of Oxfordshire.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Why has my new-build shower seal failed already?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for most snagging lists, longer for a run of plots. In a small place like North Moreton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Each area is checked and left with its cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
After the cure time, these simple habits help:
- Ventilate bathrooms well, especially in the first year
- Don’t seal over failed sealant yourself
- Get a leaking seal dealt with right away
- Check bath and shower seals every few months as the house settles
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
Signs you need new build mastic in North Moreton
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
If you can see any of these, it’s time to have the joints looked at:
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
- Gaps between new skirting and floors
- New-build shower sealant that has already split
For new homes near Didcot Parkway station, it’s worth checking the sealant early, while snags are still fresh.
