New build mastic in Sprig's Alley, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. Common call-outs are for leaking shower tray seals in a new home and joints pulling apart as timber shrinks, on skirting & floors, bathrooms & en suites and kitchens.
Around Sprig's Alley, 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.

Sprig's Alley questions
Do you work for landlords with property near Saunderton station?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you do new build mastic in Sprig's Alley?
Yes. Our work covers London and the South East, and Sprig's Alley is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Who should fix failed sealant in a new build?
Start with the builder if you are in the snagging or warranty period. Once that is done, or if they won’t put it right, we will cut it out and reseal it.
Why has my new-build shower seal failed already?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you guarantee your work?
Yes. All our work carries our 12-month guarantee.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
When to call us in Sprig's Alley
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
These are the problems we are asked about most:
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
Around Sprig's Alley, as everywhere, new build mastic is only as good as the preparation behind it.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What affects the cost of new build mastic
There’s no set price list. The quote depends on:
- The old material and how stubborn it is
- Whether the work is at height
- Which sealant suits the joint
- When we can work, for business premises
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The type of property
- The address or postcode of the job
- The problem you’ve noticed
- The rough size of the job
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.
What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or send us an email with a few pictures and we’ll tell you. Around Sprig's Alley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We’ll plan around viewing times.
What we do, step by step
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Sprig's Alley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on
