Combe: your questions answered
Can you help a landlord with a rental near Combe station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Can you do new build mastic in Combe?
Yes. Our work covers London and the South East, and Combe is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
How do I get a quote for new build mastic in Combe?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
Should I wait before resealing?
Any seal that is leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
About our new build mastic in Combe
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. If you’re dealing with gaps behind new kitchen upstands and frame joints opening as the plaster dries, we can put it right, on bathrooms & en suites, skirting & floors and plot handovers alike.
Older homes in small places like Combe often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job, whatever its size.

New build mastic in Combe: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Combe station, it’s worth checking the sealant early, while snags are still fresh. In and around Combe, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we can’t put right
We will always be straight with you, so here’s what sealant can’t fix:
- Your warranty claim itself, which is between you and the builder

- Damaged fittings that need replacing
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Avoid scourers and strong chemicals on sealant
- Don’t seal over failed sealant yourself
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Combe 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Why it’s worth doing now in Combe
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Around Combe, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.
