About our mastic sealing in Stratfield Saye

Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. 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. If you’re dealing with complaints coming in block by block and water getting in round frames after rain, we can put it right. A single leaking joint is often how a building in Stratfield Saye first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Owners and agents with buildings around smaller places such as Stratfield Saye tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What we are called out for in Stratfield Saye

Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

It’s worth sending us details if you spot any of the following:

  • Leaks at window and door perimeters
  • Open joints in brickwork or panels
  • Damaged joints in communal entrances and corridors
  • Complaints coming in block by block

Historic properties like Stratfield Saye House, 1.1 miles east of Stratfield Saye, show the age of some local stock, where frame mastic must suit soft brick or stone.

Our contractor checklist

What sets the cost

Each job is priced on its own details. The main factors are:

  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Induction, permit and paperwork requirements

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • Access details, including height
  • Clear photographs of the problem areas

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Stratfield Saye: questions and answers

Do you cover business parks and estates near Stratfield Saye, such as Campbell Court Office Park?

Yes, sites like Campbell Court Office Park are within our area, along with the rest of Stratfield Saye. Photos and a short description are enough for a first look.

Is a smaller place like Stratfield Saye outside your area?

No. Places such as Stratfield Saye are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

How do we ask for a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Can you take on resealing for a block portfolio?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Why deal with it now?

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. Around Stratfield Saye, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Stratfield Saye 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 typically where frame mastic ages first.

If you look after a block within reach of Mortimer station (1.6 miles north-west of Stratfield Saye), frame and balcony mastic can be renewed on one programme.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Ask residents or tenants to report leaks and draughts early
  • Have the asbestos survey to hand for older buildings
  • Start inspections with the most exposed faces
  • Reduce knocks to communal area joints

If paintable sealant was used, decoration can follow once it has cured. Silicone usually can’t be painted, so keep decorators off it unless told otherwise.

One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. Rural sites near Stratfield Saye may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Point out parking and an unloading spot
  • Share your working hours and any access restrictions
  • Let us know about inductions and permits

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.
