Spring Grove: your questions answered
Can you help a landlord with a rental near Isleworth station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover Spring Grove for new build mastic?
Yes, Spring Grove is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope for a clear quote.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Can you work from my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can, and we’ll quote. We will flag anything that needs another trade.

New build mastic in Spring Grove, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first. We are often asked to deal with messy sealant that spoils new finishes and leaking shower tray seals in a new home, on kitchens, windows & doors and skirting & floors.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
All of our work is guaranteed for twelve months.

Should I try it myself first?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When it isn’t the sealant
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Movement caused by a poorly fitted tray or bath
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Windows & doors
- Kitchens
- Show homes

How we quote for new build mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The type of sealant required
- Whether old sealant or filler has to be cut out
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- The rough size of the job
- What’s wrong with the joints now
- Pictures of the joints, sent by email
To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. For a job in Spring Grove, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
How to get a quote
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.

Different surfaces, different methods
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.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.

Aftercare tips
Looking after new joints is easy:
- Use the extractor fan every time you shower
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
- Don’t seal over failed sealant yourself
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
New homes and floors in Spring Grove
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
