Why it’s worth doing now in Boreham
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 email us with a few photos. Homes in smaller places like Boreham can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

New build mastic in Boreham, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. Typical jobs include cracks appearing as a new home settles and beads laid onto grit and dust from the build, on plot handovers, bathrooms & en suites and show homes.
For a new home in or near Boreham, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
You get a 12-month guarantee, the same in Boreham as everywhere else we work.

What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- A tray or bath that is not properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

What we do, step by step
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. A visit to Boreham is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know about parking restrictions
- Tell us about any water getting in
- Move anything stored near the joints

Related advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
How the job changes by surface
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. Sealant work across the plot is covered as agreed.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.

What affects the quote in Boreham
For a quick quote, just ask. What matters most is:
- Any working-time requirements on site
- Which sealant suits the joint
- The size of the job
- Mould in or behind the old joints
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
There’s no need for technical detail. Just tell us:
- A few pictures by email, if you can
- If someone has resealed it before
- Where the property is

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or send us an email.
