What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The size of the job
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved.
New build mastic for homes and businesses in Monkwood
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. Common call-outs are for second-fix sealing on new plots and messy sealant that spoils new finishes, on skirting & floors, kitchens and show homes.
Work in a small place like Monkwood just needs the journey and access planning, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Why act early in Monkwood
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Monkwood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What new build mastic looks like in Monkwood
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.
Around Monkwood, as everywhere, new build mastic is only as good as the preparation behind it. Whether the job is in Monkwood itself or nearby, the right material for each joint matters as much as a neat finish.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Wipe joints with warm soapy water
- Do not seal over failed sealant yourself
- Wait for the cure time before using a resealed shower
- Record problems with dated pictures
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

FAQs for Monkwood
Is new build mastic in Monkwood guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Monkwood?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the number of plots. We’ll confirm how long when we quote.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.

Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first.

For outside work, also let us know about exposed walls and any outbuildings involved.
