Mastic sealing across Frensham

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

Signs you need mastic sealing in Frensham

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

These are often picked up first by site or facilities staff:

  • Draught complaints from residents or tenants
  • Patchy repairs in mismatched sealant
  • Mastic failing across several blocks on an estate
  • Cracked, hardened mastic round windows on a block

If your remit includes a building such as St Mary's CofE Aided Infant School, frame and door mastic can be programmed for the holidays.

Questions to ask before you book

  • Their approach to joint depth and backing
  • What site paperwork they can supply
  • Whether primer will be used where the manufacturer specifies it
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

About our mastic sealing in Frensham

Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms, and the failures we are asked to look at most are movement joints with sealant missing and brittle perimeter mastic across a building. Whoever orders the work in Frensham, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Frensham, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Different surfaces, different methods

External movement joints

Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

Questions we are asked in Frensham

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

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Does your area include sites such as Grovebell Industrial Estate, near Frensham?

Yes. We cover Frensham and the area around it, including industrial estates, business parks and retail parks such as Grovebell Industrial Estate. Photos and a short description are enough for a first look.

Can you plan resealing across several buildings?

We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Leaks from above rather than through a joint
  • Substrate edges that need repairing first
  • Frames that are rotten, warped or broken

If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer before you book.

Where we work in Frensham

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

Planned mastic for Frensham portfolios

Central London is about 38 miles from Frensham. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.

Landlords with units on estates such as Grovebell Industrial Estate, 2.7 miles to the north-west of Frensham, can bring frame, door and external mastic across several units into one programme. If you manage student housing near a university such as University for the Creative Arts, which lies north of Frensham, the summer turnaround is the time for mastic.
