About our mastic sealing in Stroud Green

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Stroud Green carry our 12-month guarantee. If you are dealing with a mix of products and colours from past repairs and repeated reactive repairs to the same buildings, we can help, on communal entrances and stairwells, communal kitchens and washrooms and shopfronts below residential blocks alike. Whoever orders the work in Stroud Green, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Rural conversions near places like Stroud Green often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

A 12-month guarantee applies to all our work in Essex. If an installation problem shows up, phone 01277 525 020 or email the details over and we’ll arrange a return visit.

Do you need mastic sealing in Stroud Green?

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

What tends to prompt an enquiry:

  • Window mastic that has split and shrunk
  • No planned programme for sealant
  • Occupiers reporting cold air round windows
  • Worn sealant at communal door frames

If you look after a block within reach of Rochford station, 1 mile east of Stroud Green, frame and balcony mastic can be renewed on one programme.

How to choose a sealant contractor

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Stroud Green can form part of a wider programme.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Glazing that needs replacing
  • Substrate edges that need repairing first

If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.

Where we work in Stroud Green

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

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. If others near Stroud Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Old sealant is stripped and each face prepared back to firm material.
  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.

Getting the site ready

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Let building users know which areas are affected

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Advice

What sets the cost

The price varies from site to site. It mainly depends on:

  • The size and state of each joint
  • How accessible the joints are
  • Travel to remote or island sites
  • Quantities, in metres or numbers

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.

Details that help us quote

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

  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • Access details, including height
  • A wide shot and a close-up of the area

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or use the quote form.

Frames, entrances and external joints in Stroud Green

The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. Stroud Green lies roughly 34 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.

Student blocks close to universities like University of Essex (to the south-east of Stroud Green) are easiest to work on between tenancies. Older community buildings, Church of St Mary the Virgin among them, often have frames of mixed ages whose mastic varies.

Stroud Green is about 1 mile south-west of Rochford, in Essex. Any commercial site in Stroud Green is covered. Our Essex coverage takes in 644 places. For work in that direction, see our London page, about 34 miles away.

Commercial sites across SS4 are covered for mastic joints. Just outside Stroud Green, we also work in Rochford (1 mile north-east), Hawkwell (1 mile north-west), Eastwood (1 mile south-west), Southend-on-Sea (2 miles south) and Leigh-on-Sea (3 miles south-west).

Questions we are asked in Stroud Green

Will you take on a block within reach of Rochford station?

Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

Is Stroud Green too small for you to travel to?

No. Places such as Stroud Green are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What paperwork can you provide?

We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will residents or tenants be disturbed?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

Do you guarantee the mastic work?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Is it fine to apply new sealant on top of old?

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