Facade sealing in Poundon

We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you are dealing with damp patches beside frames after rain and new sealant peeling off old mastic, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Poundon it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Poundon, building work typically 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.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Maintenance after handover

A few simple habits keep the new joints working:

  • Brief window cleaners about newly sealed joints
  • Share access with other external trades
  • Note when each elevation was last resealed
  • Keep sills, gutters and drainage paths clear

After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, 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.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Poundon are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  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 can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Installing or repairing glazing systems
  • Joints whose design needs changing by the specifier
  • Specialist high-level access methods

Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.

What we seal

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

Why deal with it now?

If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Converted and older buildings near places like Poundon tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Why appoint us

  • Over 20 years of commercial sealing
  • One number for every site we cover
  • Standard and matched colours in many product ranges
  • Matching to RAL references, product permitting

Poundon: questions and answers

Do you cover business parks and estates near Poundon, such as Tower Hill Business Park?

Yes. Our area takes in Poundon and its surroundings, with estates and business parks such as Tower Hill Business Park included. Photos and a short description are enough for a first look.

Is a hospital such as Bicester Community Hospital somewhere you can work?

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 is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

New build and refits around Poundon

Poundon is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. At about 51 miles from central London, Poundon is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Recladding or extending a unit at a site like Tower Hill Business Park, 0.7 miles west of Poundon, brings panel joints and frame perimeters into the programme. Hospital estates such as Bicester Community Hospital (4.6 miles south-west of Poundon) 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. With historic properties like Claydon House (4.5 miles east of Poundon) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Poundon is about 4 miles east of Bicester, in Buckinghamshire. Our applicators travel to Poundon for work on facade joints. Poundon is one of 308 places we cover in Buckinghamshire. For work in that direction, see our Oxford page, about 14 miles away.
