What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

New build mastic for homes and businesses in Shamley Green
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. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. If you are dealing with untidy sealant flagged on a snagging list and frame joints opening as the plaster dries, we can put it right.
Work in a small place like Shamley Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What we’re called out for in Shamley Green
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
Keep an eye out for any of the following:
- Sealant applied over dusty or wet surfaces
- Second-fix sealing on new plots
- Internal frame sealant that has split
- Gaps between new skirting and floors
In and around Shamley Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Who does the work, and how experienced they are
- What the cure time is
- How hidden problems are handled
- Whether they’re fully insured
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Record problems with dated pictures
- Do not wait for the house to settle if water is getting through
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Joints and finishes in Shamley Green homes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Chilworth station, the sealant around baths, showers and frames is worth checking in the first year or two.

What’s near Shamley Green

The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. Somewhere as small as Shamley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- 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
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- For business premises, tell us about site rules or sign-in

What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved and we will quote.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Why deal with it now?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Shamley Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Any old sealant cut out fully, not covered over
- We agree the colour with you first
- Sealant colour chosen to suit
- Domestic, commercial and hotel work
