Mastic sealing for Furneux Pelham sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Why deal with it now?

Draughts round window perimeters cost occupiers comfort and the windows normally get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Around Furneux Pelham, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

About our mastic sealing in Furneux Pelham

For blocks and buildings in Furneux Pelham and across Hertfordshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you are dealing with window mastic that has split and shrunk and communal area joints that look neglected, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Furneux Pelham, preparation and product choice get the time they need.

Owners and agents with buildings around smaller places such as Furneux Pelham 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.

Surface by surface

Tenement and older buildings

Stone needs a neutral-cure product, so we pick a grade that won’t mark it.

Commercial and mixed-use buildings

Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.

After the work

For the best life from the joints:

  • Prioritise elevations facing the weather
  • Have the asbestos survey to hand for older buildings
  • Share your contractor requirements early
  • Keep a record of when each building was resealed

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

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.

Questions about Furneux Pelham

Do you cover business parks and estates near Furneux Pelham, such as Oaks Industrial Park?

Yes. We cover Furneux Pelham and the area around it, including industrial estates, business parks and retail parks such as Oaks Industrial Park. A few photos and the unit address let us price the work.

Is Furneux Pelham off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

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.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Will residents or tenants be disturbed?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.

Frames, entrances and external joints in Furneux Pelham

Furneux Pelham is about 31 miles from central London. Managed blocks of flats are a big part of commuter-belt property. Furneux Pelham is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

If your remit includes a building such as Furneux Pelham Church of England School, frame and door mastic can be programmed for the holidays. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies. Landlords with units on estates such as Oaks Industrial Park, 1 mile to the north-east of Furneux Pelham, can bring frame, door and external mastic across several units into one programme.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Substrate edges that need repairing first
  • Leaks through the frame itself rather than the perimeter
  • Glazing that needs replacing

If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

  • Communal kitchens and washrooms

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
