Riseden: your questions answered
Can you do new build mastic in Riseden?
Yes. We work across London and the South East, and Riseden is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Is Riseden within the area you cover?
Yes, Riseden is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
What do you need from me for a quote?
Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Why has my new-build shower seal failed already?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
New build mastic in Riseden, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. If you are dealing with gaps opening as the house dries out and settles and kitchen sealant that has pulled off the wall, we can help, on kitchens, show homes and bathrooms & en suites alike.
Work in a small place like Riseden just needs the journey and access planning, and once on site, the job is the same as anywhere.
Our work is backed for twelve months.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid running a DIY bead over the old one
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What affects the cost of new build mastic
You’ll get a clear quote before any work starts. It’s based on:
- Mould in or behind the old joints
- The number of rooms or windows
- Access and height
- The amount of work
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Whether it has been sealed before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
When to call us in Riseden
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The problems people usually mention when they call include:
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
- Joints pulling apart as timber shrinks
Whether the job is in Riseden itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- What product goes in the joint
- How much experience the applicator has
- Whether you can choose the colour
- Whether they seal over old material or remove it

Other services in Riseden
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Landlords, agents and businesses in Riseden
If you manage several properties in or around Riseden, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
