Puckeridge External Mastic
Our applicators work in Puckeridge on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
About our external mastic in Puckeridge
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. We are often asked to deal with panel joints letting water in and joints pointed up with cement by mistake, across render & cladding joints, brickwork movement joints and concrete & block.
In and around Puckeridge, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Every job comes with our one-year guarantee.

How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on the building. Parking around Puckeridge is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before

Advice
What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.
What external mastic looks like in Puckeridge
With historic houses such as Much Hadham Palace (about 3.3 miles south-east) nearby, there’s older building stock in the area around Puckeridge as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Roger De Clare First CofE School, its movement joints, gutters and trims need looking after like any other building’s.

Common problems we fix in Puckeridge
Many joints fail because they were sealed too deep or with nothing behind them. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Rigid filler in a joint that should flex
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Weeds or debris growing in open joints
Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

FAQs for Puckeridge
Do you cover Puckeridge for external mastic?
Yes. We work across London and the South East, and Puckeridge is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Is Puckeridge within the area you cover?
Yes, Puckeridge is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you insured?
Yes, we’re fully insured for every job we do.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
- Keep soil, plants and ivy away from the joints
- Keep movement joints as flexible joints, not mortar
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
