Facade sealing for businesses in Letcombe Bassett

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

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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

About our facade sealing in Letcombe Bassett

Managing agents and owners in Letcombe Bassett 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 are dealing with facade joints cracked through the middle and old perimeter mastic that has dried out, we can help, whatever the surface. Most enquiries from Letcombe Bassett start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Letcombe Bassett, 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 stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Commercial clients in Letcombe Bassett

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

How the quote is worked out

These are the things that shape the price:

  • Induction, permit and paperwork requirements
  • Phasing around occupants
  • Which sealant the job calls for
  • Travel to remote or island sites

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • The postcode of the building
  • The type of building and who uses it
  • A wide shot and a close-up of the area

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send details through our quote form with what you know.

Contractors’ notes for Letcombe Bassett

Letcombe Bassett lies roughly 59 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Rainfall across the South East, Letcombe Bassett included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

On a healthcare site such as Wantage Community Hospital (2.6 miles north-east of Letcombe Bassett), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. New units and refits on sites such as W&G Industrial Estate (to the north of Letcombe Bassett) need their panel and perimeter joints sealed to the specification.

Letcombe Bassett is about 3 miles south-west of Wantage, in Oxfordshire.

Why act early in Letcombe Bassett

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. For buildings around smaller places like Letcombe Bassett, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Insist on a full cut-out when joints are renewed
  • Confirm the survey covers external sealants in older buildings
  • Keep pressure washers away from fresh sealant
  • Combine resealing with other works that need access

Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Letcombe Bassett can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Point out any areas we must not close
  • Share the asbestos register for older buildings
  • Let us know about inductions and permits

Common questions from Letcombe Bassett clients

Would you work within a site like Wantage Community Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Letcombe Bassett too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you replace windows or glass?

No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Which sealant do you use on facades?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

What do you charge?

Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or use the quote form.
