Facade sealing in Nashes Green

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

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Note when each elevation was last resealed
  • Clear debris that holds water against joints
  • Brief window cleaners about newly sealed joints
  • Check the asbestos register before old mastic is disturbed

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

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Facade sealing in Nashes Green

Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, so the price covers the real job. If you have failed seals around shopfront and entrance frames and air leaks through failed facade joints, we can put it right. Facilities teams, main contractors and managing agents in Nashes Green 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 Nashes Green 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.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Providing access systems for the work
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Whether old sealant has to be cut out first
  • The product specified
  • How much there is to seal
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Where the site is, with the postcode
  • When you need the work done
  • The type of building and who uses it
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or email a schedule or drawings.

Nashes Green: questions and answers

Is Nashes Green too small for you to travel to?

Not at all. Nashes Green is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you fit the mastic around our build programme in Nashes Green?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Nashes Green need work, visits can be combined. A fixed quote is given before anything starts.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Share your working hours and any access restrictions
  • Confirm the product named in the specification

General trades versus a specialist

Certain joints really need a specialist: for example 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.

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

Facades, frames and programmes in Nashes Green

Nashes Green sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. Central London is about 46 miles from Nashes Green. 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.

Historic houses such as Hall Place, 3.3 miles to the south of Nashes Green, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. On a healthcare site such as Alton Community Hospital, which lies south-east of Nashes Green, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
