Facade sealing in Winnall, done properly
Managing agents and owners in Winnall ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have new sealant peeling off old mastic and draughts around frames and panels, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Winnall it comes down to the same thing: the right product in a properly prepared joint.
For a contractor on a smaller site near Winnall, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send details through our quote form and we will come back to it.

When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Damp caused by condensation inside the building
- Movement beyond what any sealant can handle
- Installing or repairing glazing systems
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
What we seal
- Stone and brick facade joints

How the job changes by surface
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

Contractors’ notes for Winnall
Winnall is about 60 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Rainfall across the South East, Winnall included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
Projects at colleges like Peter Symonds College, 1.2 miles to the west of Winnall, tend to run to term dates, so the mastic is planned tightly. When units on a site such as Easton Lane Business Park, less than half a mile to the west of Winnall, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Winnall is about 1 mile north-east of Winchester, in Hampshire. Any commercial site in Winnall is covered. 723 places across Hampshire fall within our area, Winnall among them. Sites around Southampton have their own page, roughly 11 miles from Winnall.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Several jobs near Winnall can be grouped on one trip. Mention the building’s opening times and we will work within them.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Before we start on site
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot
- Flag any permit to work we’ll need

Leave it or put it right?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. For buildings in places like Winnall, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Pricing facade joints depends on quantities, condition and access. Ask us for a fixed quote.

What we are called out for in Winnall
The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.
Things that usually lead to an enquiry:
- Discoloured or dirty facade joints
- Previous reseals run over old sealant
- Weathered facade joints that have lost their grip
- Facade joints cracked through the middle
For a contractor working at a hospital such as Leigh House Hospital (0.6 miles east of Winnall), perimeter and facade sealing is planned around patients and deliveries.
Questions to ask before you book
- The named product and why it was chosen
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How long is the guarantee, and what does it include?
- Whether primer will be used where the manufacturer specifies it
Aftercare for building managers
For the best life from the joints:
- Report water ingress at frames as soon as it shows
- Inspect facade joints on a regular cycle
- Record the product and colour used on each elevation
- Insist on a full cut-out when joints are renewed
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
Your questions answered
Do you take on work at healthcare sites like Leigh House Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you plan work around the academic year at somewhere like University of Winchester?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
