About our new build mastic in East Ilsley
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. We work on show homes, bathrooms & en suites and kitchens, and the jobs we see most are cracks appearing as a new home settles and sealant applied over dusty or wet surfaces.
In a village or hamlet like East Ilsley, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Joints and finishes in East Ilsley homes

What affects the cost of new build mastic
For a quick quote, just ask. The main things that affect it are:
- When we can work, for business premises
- How many rooms, windows or areas are involved
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
Before you ask for a quote, have a think about:
- The type of property
- A few pictures by email, if you can
- Roughly how big the job is
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

How the visit works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. In a small place like East Ilsley, access is normally 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.
- We clean off dust from the build and prime the surfaces where the product needs it.
- 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
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Advice
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. In a small place like East Ilsley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Use the extractor fan every time you shower
- Resist patching a failed seal with a tube from the DIY shop
- Do not wait for the house to settle if water is getting through
- Put sealant faults on your snagging list early
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Questions from East Ilsley
Is new build mastic in East Ilsley guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like East Ilsley?
Yes. East Ilsley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
