About our mastic sealing in Janetstown

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. We work on window and door perimeters on blocks, communal entrances and stairwells and shopfronts below residential blocks, and what we’re called in for most is old repairs sealed over failed mastic and occupiers reporting cold air round windows. Whoever orders the work in Janetstown, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In smaller Scottish places like Janetstown, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic usually fails first.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Have the asbestos survey to hand for older buildings
  • Protect low-level joints in entrances
  • Plan resealing building by building rather than complaint by complaint
  • Mention RAMS, insurance or CSCS requirements up front

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Where we can, we combine work around Janetstown with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use

Related advice

Commercial clients in Janetstown

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Surface by surface

Estate-wide resealing programmes

Housing associations and agents often manage many similar blocks. We quote building by building and work through them in turn.

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Why act early in Janetstown

Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Why us?

  • Our applicators hold CSCS cards
  • Colours confirmed for the specified product
  • One number for every site we cover
  • Sealing commercial buildings since 2005

Take a look at our cost guide and our accreditations.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For owners and agents in Janetstown

The sea is no more than about 3 miles from Janetstown. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. The east of Scotland, where Janetstown is, gets less rain than the west. Frost and condensation on winter mornings can still delay outside mastic. Programmes allow for that

For a school such as Thurso High School, perimeter mastic on windows and doors is a holiday job. If you look after a block within reach of Thurso station (2.4 miles north-east of Janetstown), frame and balcony mastic can be renewed on one programme.

Questions we are asked in Janetstown

We manage a building near Thurso station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Is Janetstown too far out for you?

Not at all. Janetstown is within our area. We cover the whole of Scotland. Good photographs up front let us bring everything on the first visit.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
