About our external mastic in Longfield Hill
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We are often asked to deal with joints with sealant missing in places and moss and dirt in joints with no sealant left, on copings & trims, render & cladding joints and joints between brick and frames.
In a village or hamlet like Longfield Hill, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a one-year guarantee, so you’re covered after we’ve gone.

Questions from Longfield Hill
I let a flat near Meopham station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Will you come out to Longfield Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
What is backing rod for?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
How we quote for external mastic
We quote each job individually. This is what makes a difference:
- The old material and how stubborn it is
- The number and length of the joints
- How easy the joints are to reach
- When we can work, for business premises
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What we need to know
There’s no need for technical detail. Just tell us:
- Where the property is
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own. Simply phone 0345 464 0079 or drop us an email and describe the job.
Walls and rooflines in Longfield Hill
Historic houses like Cobham College (about 2.8 miles east) are a reminder that the area around Longfield Hill has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Meopham station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St Mildred include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What the job involves on each surface
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. Where one has been mortared, we cut it out and reseal it with sealant where it can be done safely.
How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. In a small place like Longfield Hill, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we are called out for in Longfield Hill
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Hard, crazed mastic that has stopped moving
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Movement joints with cracked, split or missing sealant
Schools such as Istead Rise Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
