Facade sealing near Cuddington

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. If others near Cuddington need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

What we need from you

  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work

Facade sealing in Cuddington, done properly

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you have draughts around frames and panels and failed seals around shopfront and entrance frames, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Cuddington it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Cuddington, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Our workmanship is guaranteed for 12 months, in Cuddington as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Different surfaces, different methods

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Avoid patch repairs on failed facade joints
  • Confirm the survey covers external sealants in older buildings
  • Walk the elevations once or twice a year
  • Keep sills, gutters and drainage paths clear

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.

Building and refurbishing in Cuddington

Rainfall across the South East, Cuddington included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 41 miles from Cuddington. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

When units on a site such as Haddenham Industrial Park, 1.3 miles to the south of Cuddington, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. New wings at hospitals like St John's Hospital, 2.4 miles east of Cuddington, bring long runs of window and panel joints to seal.

Cuddington is about 4 miles north-east of Thame, in Buckinghamshire. If you are looking for facade sealing in Cuddington, we can help. Cuddington is one of 308 places in Buckinghamshire on our list for facade joints. There’s a separate page for Oxford, about 13 miles away.

When to call us in Cuddington

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead.

Most enquiries start with something like this:

  • New sealant peeling off old mastic
  • Weathered joints at frame-to-structure perimeters
  • Draughts around frames and panels
  • Cladding panel joints that have opened up

With historic properties like Waddesdon Manor, 3.3 miles to the north of Cuddington, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Before you book anyone

  • Their plan for phasing and protecting the area
  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen

Questions to ask before you appoint anyone

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

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. Getting these wrong normally costs more in the end than doing them right.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Specialist high-level access methods
  • Render or concrete edges that have broken away
  • Replacing glass or failed glazing units

If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think before you book.

Where we work in Cuddington

Common questions from Cuddington clients

Can you work at a site such as Haddenham Industrial Park, by Cuddington?

Yes. Estates, retail parks and business parks around Cuddington, Haddenham Industrial Park among them, are all within reach. A few photos and the unit address let us price the work.

Is Cuddington too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use.
