About our construction mastic in Wellow
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over. That keeps the work right first time and saves rework. We work on floor and skirting junctions, internal decorators’ caulk and brick and block movement joints, and the failures we’re asked to look at most are perimeter gaps outside the sealant’s range and sanitary sealant damaged by following trades. Whoever orders the work in Wellow, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Wellow bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Your questions answered
Is Wellow too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can the mastic package for our job in Wellow follow the site programme?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.
Do you take on mastic snagging only?
Yes, we can. Send the snag list or photos and we’ll price it, with the work timed to your handover date.
Different surfaces, different methods
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control; we work to the specification and the manufacturer’s installation guidance.
After the work
Once the work is signed off, these steps help:
- Release areas for mastic once other trades have finished in them
- Stick to the specified sealant rather than a generic substitute
- Keep finished joints away from paint, plaster and scrapers
- Keep scrapers and abrasive pads off new beads
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
One unsealed frame can let water into finished internal areas. That normally means redoing finishes in a completed area and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we’ve sealed
- Oversized gaps that need packing or adjustment by others
If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think.
Surfaces we seal
- Internal decorators’ caulk
- Brick and block movement joints
- Cladding and panel joints
- Window and door perimeters
- Sanitary and kitchen joints
- Floor and skirting junctions
Mastic packages on Wellow sites
Wellow is within about 2 miles of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Wellow sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
With historic properties like Mottistone Manor, 2.8 miles south of Wellow, in the area, refurbishment work often meets old masonry that needs compatible sealants. For contractors at a school such as Shalfleet Church of England Primary School, sealing has to be finished before term starts.
Wellow is about 6 miles south-east of Lymington, in the Isle of Wight. We cover Wellow, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our the Isle of Wight coverage takes in 125 places, large and small. Our Southampton page has more on work in that area, about 16 miles away.
We cover the PO41 postcode districts for mastic packages. We also cover Thorley Street (1 mile north-west), Ningwood (1 mile east), Thorley (1 mile north-west), Newbridge (1 mile east) and Shalcombe (1 mile south) for mastic packages. Nearby towns on our patch include Newport (7 miles east), Ryde (13 miles east), Cowes (8 miles north-east), Sandown (13 miles east), Shanklin (13 miles east) and Ventnor (12 miles south-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.
Landmarks near Wellow
A little further out are Calbourne Water Mill And Rural Museum (1.7 miles south-east) and Yarmouth Castle (2.4 miles north-west). Not far away are Lymington and Keyhaven Marshes Nature Reserve and Compton Down.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Quoting for work in Wellow
To price the job, we consider:
- How accessible the joints are
- Removal of failed or old sealant
- The total length or number of joints
- Distance, for remote addresses
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- Clear photographs of the problem areas
- The product your specification calls for
- Access details, including height
- Rough lengths or quantities, or drawings if you have them
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or send photos by email.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Wellow need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits
