Facade sealing across New Copse

Facade sealing in New Copse

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. If you’re dealing with cladding panel joints that have opened up and perimeter sealant that has split or peeled away, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in New Copse it comes down to the same thing: the right product in a properly prepared joint.

In the countryside around places like New Copse, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

New Copse: questions and answers

Is New Copse off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is Lower Soldridge Business Park, near New Copse, within your area?

Yes, sites like Lower Soldridge Business Park are within our area, along with the rest of New Copse. Photos and a short description are enough for a first look.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Do you offer coloured sealant?

Often, 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.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Providing access systems for the work
  • Joints too narrow for the movement they take, which need redesign
  • Cracked or spalling substrates that need repair before sealing

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.

What affects the price in New Copse

Quotes vary with the job. Expect it to depend on:

  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • The product specified

Pricing facade joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Whether the building will be occupied during the work
  • When you need the work done
  • Specification clauses that apply
  • Whether an asbestos survey exists

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around New Copse can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Investigate damp beside windows promptly
  • Avoid harsh cleaners on facade sealant
  • Note when each elevation was last resealed
  • Inspect facade joints on a regular cycle

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Facades, frames and programmes in New Copse

Rainfall across the South East, New Copse 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. At about 49 miles from central London, New Copse is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

Historic houses such as Bentworth Hall, 0.9 miles north-east of New Copse, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When units on a site such as Lower Soldridge Business Park, 1.8 miles south of New Copse, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. New wings at hospitals like Alton Community Hospital (3.2 miles east of New Copse) bring long runs of window and panel joints to seal.
