DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
About our new build mastic in Mockbeggar
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Common call-outs are for sealant that never bonded to the surface and smeared, uneven beads picked up at snagging, on plot handovers, bathrooms & en suites and kitchens.
Around Mockbeggar, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
You get a 12-month guarantee, the same in Mockbeggar as everywhere else we work.

When to call us in Mockbeggar
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Signs it’s time to call us include:
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
Whether the job is in Mockbeggar itself or nearby, the right material for each joint matters as much as a neat finish.

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Joints and finishes in Mockbeggar homes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

The process
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Mockbeggar, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
How to prepare
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

What affects the quote in Mockbeggar
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- Access and height
- Whether there’s mould to deal with
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Where the property is
- What’s wrong with the joints now
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
- Act quickly if a seal starts to leak
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
