New build mastic for homes and businesses in Alkerton
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. If you are dealing with beads laid onto grit and dust from the build and plot mastic for developers ahead of handover, we can put it right.
Older homes in small places like Alkerton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job.

Common questions in Alkerton
Is there a guarantee on new build mastic in Alkerton?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Alkerton within the area you cover?
Yes, Alkerton is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Common problems we fix in Alkerton
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Joints pulling apart as timber shrinks
- Gaps between new skirting and floors
In and around Alkerton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How we quote for new build mastic
There’s no set price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- The product the joint needs
- Working hours on commercial sites
- Any mould that needs treating
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Landlord and commercial work in Alkerton
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
Why act early in Alkerton
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. Where a wall is exposed, as many are in small places like Alkerton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
Why Alkerton clients choose us
- Every job guaranteed for a year
- Old sealant always removed completely
- Colour agreed with you before any work starts
- A choice of colours where the product allows
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Alkerton 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 start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- 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.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
