About our mastic sealing in Gundleton
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 draughts at frames across a block and estate-wide sealant that is simply worn out, on external wall and movement joints, window and door perimeters on blocks and communal entrances and stairwells. Whoever orders the work in Gundleton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Gundleton, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

For owners and agents in Gundleton
Central London is about 52 miles from Gundleton. Managed blocks of flats are a big part of commuter-belt property. 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 usually need attention first.
If your remit includes a building such as Perins School, frame and door mastic can be programmed for the holidays. Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.

What shapes the price:
- How much there is to seal
- The product specified

- Site requirements such as inductions and permits
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- How the joints are reached, and at what height

- Asbestos survey details if the building is older
- Any specification or named product

What the job involves on each surface
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.

Questions we’re asked in Gundleton
Does your area include sites such as Lower Soldridge Business Park, near Gundleton?
Yes. Our area takes in Gundleton and its surroundings, with estates and business parks such as Lower Soldridge Business Park included. Photos and a short description are enough for a first look.
Is a smaller place like Gundleton outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Signs you need mastic sealing in Gundleton
The edges of the material itself sometimes break away for example where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.
What tends to prompt an enquiry:
- Estate-wide sealant that is simply worn out
- Occupiers reporting cold air round windows
- Brittle perimeter mastic across a building
- Damaged joints in communal entrances and corridors
Older buildings near Gundleton, from historic houses such as Hinton Ampner House (4 miles south of Gundleton) to more modest stock, need compatible products when frames are resealed.
What your quote should include
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
- What site paperwork they can supply
- Do they follow the manufacturer’s priming guidance?
Keeping the joints sound
A few simple habits keep the new joints working:
- Start inspections with the most exposed faces
- Protect low-level joints in entrances
- Share the asbestos register when you send details
- Plan resealing building by building rather than complaint by complaint
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
