Are you ARBOMaster approved?

It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
About our new build mastic in Dawesgreen
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on kitchens, windows & doors and skirting & floors, and people most often call us about plot mastic for developers ahead of handover and gaps behind new kitchen upstands.
Around Dawesgreen, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Can I do it myself?
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, and the work is guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We will plan around viewing times.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
What new build mastic looks like in Dawesgreen
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Betchworth station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Dawesgreen, as everywhere, new build mastic is only as good as the preparation behind it.

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Structural cracks in walls or ceilings
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

What affects the quote in Dawesgreen
There’s no set price list. The quote depends on:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Access and height
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- A few pictures by email, if you can
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
If you’re in Dawesgreen and need new build mastic, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Use the extractor fan every time you shower
- Photograph failed sealant before it’s redone
- Get a leaking seal dealt with right away
- Don’t seal over failed sealant yourself
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
The process
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Dawesgreen needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- 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’re given the cure time.
How to prepare
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
