Brockenhurst questions
Will you come out to Brockenhurst?
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.
Can you do new build mastic in Brockenhurst?
Yes, Brockenhurst is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
How much does new build mastic cost in Brockenhurst?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
New build mastic for homes and businesses in Brockenhurst
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. If you’re dealing with messy sealant that spoils new finishes and internal frame sealant that has split, we can put it right, on kitchens, skirting & floors and windows & doors alike.
Homes around Brockenhurst range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Looking after it afterwards
So the new joints stay in good condition:
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
- Keep photos and emails about snagging items
- Put sealant faults on your snagging list early
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a job in Brockenhurst, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Common problems we fix in Brockenhurst
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Look out for any of the following:
- Untidy sealant flagged on a snagging list
- Worktop and upstand sealant coming away
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
For new homes near Brockenhurst station, it’s worth checking the sealant early, while snags are still fresh.

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Different surfaces, different methods
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
