Facade sealing in Marshborough

Managing agents and owners in Marshborough ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on window and door perimeters, cladding panel joints and coping and flashing joints, and what we are called in for most is air leaks through failed facade joints and old perimeter mastic that has dried out. Whoever orders the work in Marshborough, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In the countryside around places like Marshborough, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Questions about Marshborough

Can you work at a site such as Birnham Farm Business Centre, by Marshborough?

Yes. Our area takes in Marshborough and its surroundings, with estates and business parks such as Birnham Farm Business Centre included. A few photographs and the unit address let us price the work.

Is a smaller place like Marshborough outside your area?

No. Places such as Marshborough are covered as much as the big towns. 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.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Contractors’ notes for Marshborough

There are a number of hotels within about 2 miles of Marshborough. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

School extensions, at buildings such as Sandwich Technology School, usually run to the summer holidays, mastic included. When units on a site such as Birnham Farm Business Centre (to the south-west of Marshborough) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Advice

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Providing access systems for the work
  • Render or concrete edges that have broken away
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer.

Surfaces we seal

  • Shopfront frames
  • Stone and brick facade joints
  • Coping and flashing joints
  • Perimeter joints where frames meet the structure
  • Cladding panel joints
  • Window and door perimeters

Commercial clients in Marshborough

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Investigate damp beside windows promptly
  • Brief window cleaners about newly sealed joints
  • Confirm the survey covers external sealants in older buildings
  • Combine resealing with other works that need access

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones behind the facade.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

When to call us in Marshborough

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

Typical triggers for a call:

  • Weathered joints at frame-to-structure perimeters
  • Leaks at window and door perimeters
  • Draughts around frames and panels
  • Cladding panel joints that have opened up

For a contractor at a hotel such as The Lion Hotel (1.2 miles north-west of Marshborough), the mastic often has to be finished before a reopening date.
