FAQs for High Garrett
Is High Garrett within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Braintree station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.
New build mastic for homes and businesses in High Garrett
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. If you have gaps behind new kitchen upstands and skirting joints opening in the first winter, we can help.
Older homes in small places like High Garrett often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

- Messy sealant that spoils new finishes
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
- Internal frame sealant that has split
Around High Garrett, as everywhere, new build mastic is only as good as the preparation behind it.

What the job involves on each surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. Somewhere as small as High Garrett, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

Advice
What affects the quote in High Garrett
We quote each job individually. This is what makes a difference:
- The product the joint needs
- The old material and how stubborn it is
- The number of rooms or windows
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- Photos by email, if that is easy
- The type of property
- The address or postcode of the job
For a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Cracked trays, tiles or worktops
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before you book.
