Mastic sealing in Grafham, done properly
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 and we quote and schedule each building in turn. We work on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints, and the failures we’re asked to look at most are estate-wide sealant that is simply worn out and occupiers reporting cold air round windows. Looking for mastic applicators who cover Grafham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In and around smaller places like Grafham, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Frames, entrances and external joints in Grafham
Central London is about 30 miles from Grafham. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Grafham included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Historic properties like Chilworth Manor (to the north of Grafham) show the age of some local stock, where frame mastic must suit soft brick or stone. Older community buildings, Church of St Andrew among them, often have frames of mixed ages whose mastic varies.

Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Grafham need work, visits can be combined. A fixed quote is given before anything starts.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Flag any permit to work we will need
- Tell staff and tenants when we will be in
- Send any specification or drawings in advance

Questions we are asked in Grafham
Is Grafham off your patch?
Not at all. Grafham is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you quote for a block close to Chilworth station?
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.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Who decides which product is used?
If the job is specified, we follow the specification. 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?
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.
Why it’s worth doing now in Grafham
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. For buildings around smaller places like Grafham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why us?
- Commercial sealant work since 2005
- Fully insured
- Colours chosen to suit frames, cladding or finishes where possible
- Colours confirmed for the specified product
See our cost guide or how we’re accredited.
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Keep a record of when each building was resealed
- Start inspections with the most exposed faces
- Share the asbestos register when you send details
- Ask residents or tenants to report leaks and draughts early
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Frames that are rotten, warped or broken
- Misted or failed double-glazed units
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly.

Do you need mastic sealing in Grafham?
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Any of the following is a good reason to get the joints checked over:
- Worn sealant at communal door frames
- Estate-wide sealant that is simply worn out
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
Buildings close to stations like Chilworth station (to the north of Grafham) are often flats over shops, with frame mastic to keep sound.
Questions to ask before you book
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
- How long is the guarantee, and what does it include?
- Will CSCS-carded applicators be on site?
