Mastic sealing for Peaslake sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Mastic sealing in Peaslake

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. Most enquiries involve no planned programme for sealant and movement joints with sealant missing, across communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Peaslake, preparation and product choice get the time they need.

Rural conversions near places like Peaslake often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

What the job involves on each surface

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.

Common questions from Peaslake clients

Is Peaslake too far out for you?

No. Places such as Peaslake are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

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

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

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.

What about access for upper-floor joints?

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

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you supply RAMS and insurance details?

We’re 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.

Why act early in Peaslake

Draughts round window perimeters cost occupiers comfort and the windows usually get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Around Peaslake, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

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 and we will explain how it’s made up.

Why us?

  • Old sealant cut out, never sealed over
  • CHAS accredited contractor
  • 12-month guarantee on workmanship
  • RAL and finish matching where the product range allows

Common problems we fix in Peaslake

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.

If one of these sounds familiar, it’s time for a closer look:

  • Patchy repairs in mismatched sealant
  • Damaged joints in communal entrances and corridors
  • Occupiers reporting cold air round windows
  • Repeated reactive repairs to the same buildings

Buildings close to stations like Gomshall station, 1.8 miles north of Peaslake, are often flats over shops, with frame mastic to keep sound.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Health and safety accreditation such as CHAS
  • What site paperwork they can supply
  • Their approach to joint depth and backing

Our contractor checklist

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Peaslake are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Preparing the site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings

Get a fixed quote

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to phone 01277 525 020 or email the details over.

Advice

Blocks and managed buildings in Peaslake

Peaslake sits in one of the drier corners of the country, the South East. 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. Peaslake lies roughly 26 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

Older buildings near Peaslake, from historic houses such as Chilworth Manor (4.2 miles north-west of Peaslake) to more modest stock, need compatible products when frames are resealed. Older community buildings, Church of St Mark among them, often have frames of mixed ages whose mastic varies.

Peaslake is about 6 miles south-west of Dorking, in Surrey. Peaslake sits inside our coverage and the rest of Surrey, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 379 places in Surrey. Our London page has more on work in that area.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Broken glass or failed sealed units
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think.
