How we handle facade sealing in Scaynes Hill

Managing agents and owners in Scaynes Hill ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on cladding panel joints, shopfront frames and window and door perimeters, and the usual reasons a site gets in touch are water coming in around window frames and staining on stone next to old sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Scaynes Hill, preparation and product choice get the time they need.

Construction in and around smaller places such as Scaynes Hill is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

How the quote is worked out

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

  • The product specified
  • Site requirements such as inductions and permits
  • How accessible the joints are
  • Location, for remote and island sites

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

However big the job, the same details help:

  • Any specification or named product
  • Anything awkward about access or site hours
  • What the building is and how it’s used
  • The asbestos register, for older buildings

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.

Surface by surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints rather than the system it surrounds.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Scaynes Hill may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Let us know about inductions and permits

Facade sealing around Scaynes Hill: how the place shapes the job

The South East is one of the drier parts of the UK. 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. Central London is about 35 miles from Scaynes Hill. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.

For contractors at a college like Haywards Heath College, 2.7 miles north-west of Scaynes Hill, perimeters and internal sealant are timed for the holidays. On a healthcare site such as Princess Royal Hospital (1.6 miles west of Scaynes Hill), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Building work at universities like University of Sussex (to the south of Scaynes Hill) is often timed for the summer, mastic included.

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Do you use silicone for external joints?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Does weather matter for sealant 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. Indoors, the weather is rarely a problem.

Keeping the joints sound

To get the most from the new sealant:

  • Insist on a full cut-out when joints are renewed
  • Add perimeter sealant to planned maintenance checks
  • Ask about asbestos in pre-2000 mastic
  • Brief window cleaners about newly sealed joints

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
