Facade sealing for businesses in North Berwick

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

How the job changes by surface

Window and door perimeters

Window and door perimeters make up most facade sealing work. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

How we handle facade sealing in North Berwick

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you have sealant pulling away from frames or panels and previous reseals run over old sealant, we can help. Searching for sealant specialists in North Berwick? We have been sealing commercial buildings since 2005.

For a site around North Berwick, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

Mastic packages on North Berwick sites

North Berwick lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. North Berwick is in the east of Scotland, which is drier than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. External dates keep a little give.

New units and refits on sites such as Heugh Road Industrial Estate, 1 mile east of North Berwick, need their panel and perimeter joints sealed to the specification. Hotels like Folly Hotel (to the north of North Berwick) rarely close for long, so refurbishment mastic is phased floor by floor. Hospital estates such as Edington Cottage Hospital, less than half a mile to the east of North Berwick, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

North Berwick is about 18 miles east of Kirkcaldy, in East Lothian.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Report water ingress at frames as soon as it shows
  • Plan facade sealing alongside redecoration
  • Walk the elevations once or twice a year
  • Check that rainwater leaves the facade the way it was designed to

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards with a compatible product.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Travel to smaller Scottish places like North Berwick is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Flag any permit to work we will need
  • Explain the parking and delivery arrangements

Advice

Questions about North Berwick

Is Heugh Road Industrial Estate, near North Berwick, within your area?

Yes. Estates, retail parks and business parks around North Berwick, Heugh Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is North Berwick too far out for you?

No. Small places get the same service as large ones. We cover the whole of Scotland. Good photos up front let us bring everything on the first visit.

Do you use silicone for external joints?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do you offer coloured sealant?

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

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Can you just add new sealant on top?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.

What sets the cost

To price the job, we consider:

  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition

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.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • Whether an asbestos survey exists
  • The site address and postcode
  • Your programme or deadline

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
