Mastic sealing for Telham sites

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

Mastic sealing in Telham, done properly

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. We work on communal entrances and stairwells, communal kitchens and washrooms and window and door perimeters on blocks, and what we’re called in for most is window mastic that has split and shrunk and failed external movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Telham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around smaller places like Telham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Cost factors for mastic joints

A fixed quote reflects the actual work. It allows for:

  • How accessible the joints are
  • Which sealant the job calls for
  • The site’s rules and procedures
  • Location, for remote and island sites

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • Your programme or deadline
  • Specification clauses that apply

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Looking after the joints

For the best life from the joints:

  • Check sealant joints during planned building inspections
  • Encourage occupiers to report problems at frames
  • Avoid piecemeal callouts where you can
  • Track which buildings were done and when

Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it unless told otherwise.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Frames, entrances and external joints in Telham

Telham is about 49 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

Site managers at schools like Claverham Community College can fit frame mastic into the summer works. Property owners at sites such as Rutherford Business Park, 1.3 miles to the north of Telham, can have mastic renewed between lettings.

Telham is about 4 miles north-west of Hastings, in East Sussex. We cover commercial sites throughout Telham. We work across 308 places in East Sussex, from busy centres to rural villages. Our Brighton page has more on work in that area, about 28 miles away.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Water coming in from the roof or rainwater goods
  • Leaks through the frame itself rather than the perimeter
  • Misted or failed double-glazed units

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Joints and surfaces we work on

  • Window and door perimeters on blocks
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Balcony and threshold joints
  • Shopfronts below residential blocks

Do you need mastic sealing in Telham?

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.

If one of these sounds familiar, it’s time for a closer look:

  • Window mastic that has split and shrunk
  • Patchy repairs in mismatched sealant
  • Failed external movement joints
  • Draughts at frames across a block

With historic buildings such as Durhamford Manor, 2.4 miles north of Telham, in the wider area, owners of older properties around Telham should expect mastic to need a product that suits old masonry.

Common questions from Telham clients

We manage a building near Battle 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 will quote and plan to suit.

Will you take on work at estates like Rutherford Business Park, close to Telham?

Yes. Our area takes in Telham and its surroundings, with estates and business parks such as Rutherford Business Park included. A few photos and the unit address let us price the work.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Can you reseal a whole block or estate?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

On site: what to expect

Before we leave any area, 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. For work around Telham, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Send your site hours and access windows
  • Warn occupants and staff about the work
  • Move anything stored against the joints
