Broadstone: your questions answered
Is Broadstone within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Lenham station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
How long does remedial resealing take?
The number of joints and layers decides it. You will have a timescale before any work begins.
Does remedial work come with a guarantee?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
My shower still leaks after a reseal. Can you sort it?
Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.

What affects the cost of remedial sealant
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- How much there is to do
- Working hours on commercial sites
- How easy the joints are to reach
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
To make quoting easier, please include:
- If someone has resealed it before
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- A tray or worktop that needs refixing first
- Plumbing leaks behind walls or under trays
- Water damage behind tiles that needs a tiler
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Broadstone homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Around Broadstone, as everywhere, remedial sealant is only as good as the preparation behind it.

Different surfaces, different methods
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, which we’ll point out.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The process
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. Somewhere as small as Broadstone, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Why deal with it now?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, so the joint can be treated and resealed. Around Broadstone, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
