DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How we handle new build mastic in Colgate
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Common call-outs are for joints pulling apart as timber shrinks and sealant that never bonded to the surface, on kitchens, skirting & floors and plot handovers.
Somewhere as small as Colgate, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All our work is covered by a one-year guarantee, wherever you are in West Sussex.

Colgate: your questions answered
Is Colgate within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Faygate station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Do you work for developers?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved and we’ll quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Surface by surface
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. We will plan around viewing times.
What we cannot put right
We won’t take on work that will not last, so these are the limits:
- Damaged fittings that need replacing
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on

What affects the cost of new build mastic
You will get a clear quote before we start. It takes into account:
- The old material and how stubborn it is
- How easy the joints are to reach
- How many areas need sealing
- The product the joint needs
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- The address or postcode of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or send us an email.
Why act early in Colgate
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Older cottages and farmhouses around Colgate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

- Colour picked to suit the job

Landlord and commercial work in Colgate
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours in a single home in most cases. Somewhere like Colgate needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
Getting ready for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
Ask for a quote
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or send us an email.
