Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When to call us in Winchester
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
If one of these sounds familiar, it’s time for a closer look:
- Water coming in around window frames
- Unsightly perimeter sealant on a visible elevation
- New sealant peeling off old mastic
- Perimeter sealant that has split or peeled away
On a healthcare site such as Royal Hampshire County Hospital, 0.6 miles west of Winchester, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What your quote should include
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
About our facade sealing in Winchester
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on commercial buildings in Winchester. Where sealant is the specified fix, we also take on coping and flashing joints. Site teams most often ask us about weathered facade joints that have lost their grip and leaks at window and door perimeters, on perimeter joints where frames meet the structure, cladding panel joints and shopfront frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Winchester it comes down to the same thing: the right product in a properly prepared joint.
Bigger sites around a town like Winchester usually want mastic phased by plot, block or floor. CSCS-carded applicators work to the site’s rules and the specification, and any snags are cleared before handover.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.
What happens if it’s left?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, so the real damage is often some distance away. Water getting in through a failed joint can damage finishes, stock and fittings, and putting that right normally costs more than the reseal. It’s worth fixing at the first sign.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Jobs in a large place like Winchester are often on business parks, retail sites or campuses with their own sign-in and permit rules. Tell us about inductions, permits and site hours so the plan fits.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Point out any areas we must not close
- Flag any permit to work we will need
- Move anything stored against the joints

Related advice
After the work
To get the most from the new sealant:
- Brief window cleaners about newly sealed joints
- Note when each elevation was last resealed
- Investigate damp beside windows promptly
- Check the asbestos register before old mastic is disturbed
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.
Questions about Winchester
Can work at a site such as University of Winchester fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Would you work within a site like Royal Hampshire County Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Which sealant do you use on facades?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start.
How much does the work cost?
Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or send photos by email with a description of the work.
Building and refurbishing in Winchester
Winchester is about 61 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Winchester has a good number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For contractors on a campus like University of Winchester, which lies west of Winchester, facade and perimeter sealing has to fit around students and term dates. For a contractor at a hotel such as Southgate Hotel (under half a mile north of Winchester), the mastic often has to be finished before a reopening date.

Quoting for work in Winchester
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Photos of the joints, close up and from further back
- Specification clauses that apply
- The site address and postcode
- Drawings or a marked-up plan, if available
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Surface by surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair first.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
