Facade sealing for commercial buildings in Penton Mewsey
Managing agents and owners in Penton Mewsey ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. We work on shopfront frames, coping and flashing joints and perimeter joints where frames meet the structure, and what we’re called in for most is old perimeter mastic that has dried out and leaks at window and door perimeters. A single leaking joint is often how a building in Penton Mewsey first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions of older rural buildings near smaller places such as Penton Mewsey 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 typically what’s needed.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

We price every job individually. The things that drive the figure:

- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
- How much there is to seal
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Questions we’re asked in Penton Mewsey
Is Penton Mewsey too small for you to travel to?
Not at all. Penton Mewsey is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work at a site such as Portway Industrial Estate, by Penton Mewsey?
Yes, sites like Portway Industrial Estate are within our area, along with the rest of Penton Mewsey. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
What do you charge?
Each job is quoted on its own details. For yours, call 01277 525 020 or email drawings and photos with a description of the work.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
How a job runs
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, with the work itself usually taking longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For work around Penton Mewsey, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Point out parking and an unloading spot
- Tell us which areas need to stay in use
- Let us know about inductions and permits

Advice
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Add perimeter sealant to planned maintenance checks
- Report water ingress at frames as soon as it shows
- Never let anyone seal over old sealant
- Keep the sealant details on the building file
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.
Signs you need facade sealing in Penton Mewsey
Adhesive failure, where the sealant peels away from one face, normally comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.
Site and facilities staff are often the first to spot these:
- Failed seals around shopfront and entrance frames
- Unsightly perimeter sealant on a visible elevation
- Patch repairs that keep failing
- Cold air coming in at window perimeters
Units on estates such as Portway Industrial Estate (1 mile south-east of Penton Mewsey) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What to look for in a quote
- Will RAMS and insurance details be available?
- The terms of the workmanship guarantee
- How the joint faces will be prepared and primed
- Will CSCS-carded applicators be on site?
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

How the job changes by surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
Contractors’ notes for Penton Mewsey
Penton Mewsey sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Penton Mewsey is about 65 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.
When a school such as Harrow Way Community School is extended or refurbished, the mastic package is often squeezed into the holidays. For contractors at a college like Andover College, which lies south-east of Penton Mewsey, perimeters and internal sealant are timed for the holidays.
