About our facade sealing in Copythorne

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. The enquiries we see most involve air leaks through failed facade joints and leaks at window and door perimeters, on perimeter joints where frames meet the structure, window and door perimeters and coping and flashing joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Copythorne, preparation and product choice get the time they need.

Sites around smaller places like Copythorne can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

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

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Copythorne are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints

Advice

What we are called out for in Copythorne

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Things that usually lead to an enquiry:

  • Weathered facade joints that have lost their grip
  • Cladding panel joints that have opened up
  • Staining on stone next to old sealant
  • Facade joints cracked through the middle

On a healthcare site such as Tatchbury Mount Hospital (1.3 miles east of Copythorne), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

  • How joint depth will be controlled
  • What the guarantee covers, and for how long
  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed

How to choose a sealant contractor

Common questions from Copythorne clients

Can you work around term dates at a campus such as Totton College?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Does your area include sites such as Mortimer Trading Estate, near Copythorne?

Yes, sites like Mortimer Trading Estate are within our area, along with the rest of Copythorne. Send details of the unit and the work through our quote form for a quick quote.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How do we ask for a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Installing or repairing glazing systems
  • Water getting in through cracked render or porous masonry
  • Specialist high-level access methods

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

Where we work in Copythorne

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What happens if it’s left?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Halls, stores and units around places like Copythorne may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Facade sealing around Copythorne: what changes locally

Copythorne is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. A 2-mile radius around Copythorne takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Hotel extensions and refits, at places such as The Bartley Lodge Hotel, 1.2 miles south-west of Copythorne, normally run between busy periods, so the sealing is squeezed into short windows. When a school such as Copythorne CofE Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

Copythorne is about 2 miles west of Totton, in Hampshire. Across the SO40 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. There’s a separate page for Southampton, roughly 7 miles from Copythorne.

Surface by surface

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.
