Gosfield: questions and answers

Is Gosfield too small for you to travel to?

No. Places such as Gosfield are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

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

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

When is resealing likely to be due?

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.

Can you take on resealing for a block portfolio?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Is asbestos a concern with old mastic?

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

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How we handle mastic sealing in Gosfield

Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you have occupiers reporting cold air round windows and open joints in brickwork or panels, we can help, on balcony and threshold joints, shopfronts below residential blocks and communal kitchens and washrooms alike. Facilities teams, main contractors and managing agents in Gosfield tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For owners with a single building near Gosfield, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Frames that are rotten, warped or broken
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Misted or failed double-glazed units

If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

What we seal

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

Mastic sealing around Gosfield: points for this area

At about 42 miles from central London, Gosfield is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide. Gosfield is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

Older buildings near Gosfield, from historic houses such as Hedingham Castle (4 miles north of Gosfield) to more modest stock, need compatible products when frames are resealed. Schools and community buildings such as Gosfield Community Primary School need frame and external mastic kept sound like any building. If you own or manage units on a site such as Whitehouse Business Park, 1.4 miles to the north-east of Gosfield, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Gosfield is about 2 miles west of Halstead, in Essex. Gosfield sits inside our coverage and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else. Gosfield is one of 644 places we cover in Essex. Sites around London have their own page, about 42 miles away.

Commercial sites across CO9 are covered. Buildings on The Street, Church Road and The Limes are within our area for mastic joints. We also cover High Garrett (2 miles south), Harrowcross (3 miles north), Beazley End (3 miles west), Almshouse Green (3 miles north-west) and Sible Hedingham (3 miles north). A short drive away, we cover Colchester (13 miles east), Chelmsford (14 miles south), Braintree (4 miles south), Maldon (15 miles south), Witham (9 miles south) and Camulodunum (12 miles east).

After the work

Keep the joints in good shape with a few simple steps:

  • Keep a record of when each building was resealed
  • Check sealant joints during planned building inspections
  • Share your contractor requirements early
  • Group repairs into a planned programme

Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.

What sets the cost

These are the things that shape the price:

  • Which sealant the job calls for
  • The size and state of each joint
  • Working within restricted access windows
  • Any access equipment needed

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • The site address and postcode
  • 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.

Commercial clients in Gosfield

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Our process

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Gosfield are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot

Getting a fixed quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Why act early in Gosfield

Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Converted and older buildings near places like Gosfield tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
