Most people get in touch after spotting one of these:
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
For new homes near Godalming station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours in a single home. For a village or hamlet like Thorncombe Street, the journey is planned in advance: 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 start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Tell us about any water getting in
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Also in Thorncombe Street
Keeping the joints in good condition
So the new joints stay in good condition:
- Do not seal over failed sealant yourself
- Keep pictures and emails about snagging items
- Raise failed sealant with the developer while you are covered
- Ventilate bathrooms well, especially in the first year
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Thorncombe Street questions
Is Thorncombe Street within the area you cover?
Yes, Thorncombe Street is covered. 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 Godalming station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
How long does new build mastic take?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We will give you a better idea when we quote.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we will quote. We’ll tell you if anything on it is not a sealant job.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Where a wall is exposed, as many are in small places like Thorncombe Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
