Facade sealing for Puttenham sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

How we handle facade sealing in Puttenham

External joints face UV, rain, temperature swings and building movement all year. 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. Site teams most often ask us about gaps between rainscreen or cladding panels and draughts around frames and panels, on shopfront frames, coping and flashing joints and cladding panel joints. Facilities teams, main contractors and managing agents in Puttenham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Sites around smaller places like Puttenham can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we’ll quote to suit.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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.

Your questions answered

Can you work at a site such as College Business Park, by Puttenham?

Yes. Estates, retail parks and business parks around Puttenham, College Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like Tindal Centre?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.

Do you install glazing systems?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. For work around Puttenham, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance

Getting a fixed quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send photos by email.

Advice

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure. Around Puttenham, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Puttenham choose us

  • Colour options checked against the specified product
  • One number for every site we cover
  • 12-month guarantee on workmanship
  • Clear, fixed quotes

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Walk the elevations once or twice a year
  • Combine resealing with other works that need access
  • Avoid patch repairs on failed facade joints
  • Ask about asbestos in pre-2000 mastic

Record the sealant type and date on the building file. Future work can then match the product and colour without guesswork.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

New build and refits around Puttenham

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 we time external mastic for dry faces and agree it with the site team. Puttenham lies roughly 35 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

On a healthcare site such as Tindal Centre (3.8 miles west of Puttenham), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. School extensions, at buildings such as Long Marston VA Church of England Primary School, usually run to the summer holidays, mastic included.

Puttenham is about 4 miles east of Aylesbury, in Hertfordshire. Our applicators travel to Puttenham for work on facade joints. Puttenham is one of 371 places in Hertfordshire on our list for facade joints. Oxford is covered too, some 23 miles away.

If your building is just outside Puttenham, we cover Astrope (1 mile east), Long Marston (1 mile north-east), Buckland (1 mile south), Aston Clinton (2 miles south) and Broughton (2 miles west). Further afield, our area takes in Hemel Hempstead (12 miles south-east), Berkhamsted (7 miles south-east), Tring (3 miles south-east), Chorleywood (15 miles south-east), Grovehill (12 miles south-east) and Woodhall Farm (12 miles south-east).

Signs you need facade sealing in Puttenham

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Site and facilities staff are often the first to spot these:

  • Discoloured or dirty facade joints
  • Hard, chalky sealant that no longer flexes
  • Previous reseals run over old sealant
  • Damp patches beside frames after rain

When units on a site such as College Business Park, 1 mile to the west of Puttenham, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What your quote should include

  • Their pre-qualification and accreditations
  • How long is the guarantee, and what does it include?
