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

Mastic sealing in Farncombe, done properly

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you have old repairs sealed over failed mastic and draught complaints from residents or tenants, we can put it right, whatever the surface. Looking for mastic applicators who cover Farncombe? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Converted and older buildings in and around Farncombe often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.

Work we carry out in Surrey comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Farncombe is a clear list of what needs doing. A fixed quote follows.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  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.

When to call us in Farncombe

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.

Site and facilities staff are often the first to spot these:

  • Old repairs sealed over failed mastic
  • Movement joints with sealant missing
  • Draught complaints from residents or tenants
  • Damp patches beside frames

Student blocks close to universities like University of Surrey - Manor Park Campus, 2.7 miles north of Farncombe, are easiest to work on between tenancies.

What your quote should include

  • Who will actually carry out the work
  • Is the sealant right for the movement and the substrate?
  • How long is the guarantee, and what does it include?
  • Will RAMS and insurance details be available?

Cost factors for mastic joints

These are the things that shape the price:

  • The total length or number of joints
  • The product specified
  • Joint width, depth and condition
  • How much existing material needs removing

A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Before you send an enquiry

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

  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Planned mastic for Farncombe portfolios

Farncombe sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Farncombe is about 30 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.

For a school such as Farncombe Church of England Infant School, perimeter mastic on windows and doors is a holiday job. If you are responsible for a building such as St John the Evangelist Church, frame and door mastic needs the same attention as any other property.

Farncombe is about 4 miles south-west of Guildford, in Surrey. If you are looking for mastic sealing in Farncombe, we can help, as we do across Surrey. Farncombe is one of 379 places we cover in Surrey. Reading is covered too, around 24 miles from Farncombe.

Why act early in Farncombe

Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. In a smaller place such as Farncombe, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

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

Why clients in Farncombe choose us

  • Coloured sealants to suit the setting, where available
  • One contact handling all your sites
  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months

Take a look at what affects the cost and how we’re accredited.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Farncombe: questions and answers

Is a smaller place like Farncombe outside your area?

No. Places such as Farncombe are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you work for managing agents with blocks near Farncombe station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

What guarantee do you give on resealing?

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

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

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.

Can you send RAMS and CSCS details before starting?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

What about access for upper-floor joints?

Every block is different. We agree access with you at quote stage so there are no surprises.

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Group repairs into a planned programme
  • Make it easy for occupiers to report draughts
  • Check sealant joints during planned building inspections
  • Protect low-level joints in entrances

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.
