What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
New build mastic for homes and businesses in Canada
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, bathrooms & en suites and windows & doors, and the jobs we see most are joints pulling apart as timber shrinks and gaps between new skirting and floors.
Work in a small place like Canada just needs the journey and access planning, and once on site, the job is the same as anywhere.
All of our work is guaranteed for twelve months.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the number of plots, including the tidy-up. Somewhere as small as Canada, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any tricky access
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

New build mastic in Canada: local notes
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.
For new homes near Romsey station, it’s worth checking the sealant early, while snags are still fresh.
Canada is about 5 miles north-west of Totton, in Hampshire. From the centre of Canada to the outskirts, new build mastic is available for homes and businesses alike. Our area takes in 683 places across Hampshire, large and small. We also work in Southampton, around 9 miles away.
Our applicators cover all of the SO51 postcode area for new build mastic. We also cover the places around Canada: West Wellow (1 mile north), Blackhill (1 mile east), East Wellow (1 mile east), Newbridge (2 miles south) and Plaitford Green (2 miles north). Larger places within reach include Winchester (14 miles north-east), Eastleigh (11 miles east), Totton (5 miles south-east), Chandler's Ford (9 miles east), Hedge End (13 miles east) and Lymington (14 miles south).
Near you in Canada
Typical jobs here are in homes near Rockingham Arms. For rail, the closest station is Romsey station, about 4.6 miles north-east of the centre. A little further out are Tatchbury Mount Hospital (3.5 miles south-east). Not far away are Copythorne Common.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Ventilate bathrooms well, especially in the first year
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
What we’re called out for in Canada
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry.
The most common problems we see are:
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
- Kitchen sealant that has pulled off the wall
Around Canada, as everywhere, new build mastic is only as good as the preparation behind it.

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Canada, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What affects the quote in Canada
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Whether there’s mould to deal with
- The size of the job
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote

Questions from Canada
Do you cover smaller places like Canada?
Yes. Canada is within the area we cover, which takes in towns, villages and rural addresses. 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 help a landlord with a rental near Romsey station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room and agree it with you.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
