About our new build mastic in Chichester
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. If you have cracks appearing as a new home settles and cracked caulk along new skirting, we can put it right.
Small business units and shops in a town like Chichester have floors that take heavy wear. Threshold and floor joints are best resealed before their edges start breaking away.
All our work is covered by a one-year guarantee, wherever you are in West Sussex.

Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Chichester they spread with every shower and every downpour. Now is the easy time to put it right.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Questions from Chichester
Can you help a landlord with a rental near Chichester station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover Chichester for new build mastic?
Yes. Our work covers London and the South East, and Chichester is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
DIY versus a professional finish
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- The type of sealant required
- Any mould that needs treating
- How many areas need sealing
- The number and length of the joints
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
To make quoting easier, let us know:
- Any access issues, like height or stairs
- Roughly how big the job is
- Whether it’s a home or a business
- Any previous sealing or DIY work
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or send us an email.
The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. In Chichester, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
How to get a quote

How to look after the new joints
Aftercare is simple:
- Put sealant faults on your snagging list early
- Avoid scourers and strong chemicals on sealant
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
