About our facade sealing in Penton Corner
Managing agents and owners in Penton Corner 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. Each job carries our 12-month guarantee. If you’re dealing with gaps between rainscreen or cladding panels and old perimeter mastic that has dried out, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Penton Corner, that means joint design, primers and backing rod as standard.
Sites around smaller places like Penton Corner can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Joints too narrow for the movement they take, which need redesign
- Render or concrete edges that have broken away
- Installing or repairing glazing systems

Contractors’ notes for Penton Corner
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Central London is about 65 miles from Penton Corner. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For contractors at a school such as Portway Junior School, sealing has to be finished before term starts. Hospital estates such as Andover War Memorial Hospital, 1.5 miles east of Penton Corner, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Further education sites such as Andover College, 2 miles east of Penton Corner, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Penton Corner is about 2 miles west of Andover, in Hampshire. Anywhere in SP11, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Penton Corner is one of 723 places we cover in Hampshire for facade joints. We also cover Southampton, some 21 miles away.

Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep sills, gutters and drainage paths clear
- Brief window cleaners about newly sealed joints
- Plan facade sealing alongside redecoration
- Report water ingress at frames as soon as it shows
Keep a note of which product went in and when. Future work can then match the product and colour.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading.
Surface by surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end with backing and a facade-grade sealant.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.
Penton Corner: questions and answers
Can you take on a job at a hospital such as Andover War Memorial Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Penton Corner too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Will rain stop the work?
Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things.
Do you replace failed glazing units?
No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If others near Penton Corner need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
Getting the site ready

- Share the asbestos register for older buildings
- Share your working hours and any access restrictions
