Is Anmore in your area for new build mastic?

Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long does new build mastic take?
A typical job takes anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
New build mastic in Anmore
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 new bead bonds properly instead of bonding to the dust. We are often asked to deal with cracked sealant around new window and door frames and kitchen sealant that has pulled off the wall, across plot handovers, bathrooms & en suites and show homes.
Work in a small place like Anmore just needs the journey and access planning, and once on site, the job is the same as anywhere.
Your job is guaranteed for a year, as with all our work.

What we are called out for in Anmore
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Any of these means the joints need attention:
- Joints pulling apart as timber shrinks
- Sealant that never bonded to the surface
- Shower seals failing in the first year or two
- Second-fix sealing on new plots
In and around Anmore, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. In a small place like Anmore, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any tricky access
- Try not to wet indoor joints just before the visit

Related advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
How the job changes by surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
What affects the cost of new build mastic
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- The amount of work
- Access and height
- The number of rooms or windows
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
To make quoting easier, please include:
- Where the property is
- A few photos by email, if you can
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
