New build mastic in Arundel: local notes

Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or isn’t dealt with, we can reseal it properly. In a smaller place like Arundel, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why book with us
- A 12-month guarantee on all work
- More than 20 years in sealant work
- Quality sealants from Arbo and Everbuild
- We agree the colour with you first

What sealant work cannot fix
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Do you need new build mastic in Arundel?
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry.
These are the problems we are asked about most:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Gaps between new skirting and floors
- Messy sealant that spoils new finishes
In and around Arundel, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

Common questions in Arundel
Do you cover smaller places like Arundel?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do new build mastic in Arundel?
Yes, Arundel is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
How do I get a quote for new build mastic in Arundel?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Where is Mr Mastic based?
We work from Crawley. We cover Arundel and the rest of West Sussex, along with the rest of our area.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we will do.
What we do, step by step
The work is kept neat and contained to the joints we are treating. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. In a smaller place like Arundel, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

Advice
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Avoid scourers and strong chemicals on sealant
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
