DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
About our new build mastic in Slindon
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for kitchen sealant that has pulled off the wall and frame joints opening as the plaster dries, across bathrooms & en suites, show homes and skirting & floors.
For a small place like Slindon, the journey and access are planned in advance, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job.

Slindon: your questions answered
Can you help a landlord with a rental near Barnham station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Can you do new build mastic in Slindon?
Yes. Our work covers London and the South East, and Slindon is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Slindon 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 look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- 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 stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

Related advice
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Report sealant problems to your builder during the snagging period
- Follow the cure time we give you
- Open a window or run the fan after bathing
- Keep pictures and emails about snagging items
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
What the job involves on each surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.

What affects the quote in Slindon
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- The amount of work
- How many rooms, windows or areas are involved
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Damaged fittings that need replacing
- Plumbing faults behind the sealant
- A tray or bath that is not properly supported, until it’s fixed
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
