How much does external mastic cost in Standon Green End?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.

Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
External mastic in Standon Green End
Low-level joints can generally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on copings & trims, façade panels and concrete & block, and common reasons people get in touch are movement joints with cracked, split or missing sealant and cracked joints where brick meets render or frames.
In a village or hamlet like Standon Green End, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, it’s backed by our 12-month guarantee.

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on the building. In a small place like Standon Green End, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.

What external mastic looks like in Standon Green End
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Much Hadham Palace (about 4.5 miles east) nearby, there’s older building stock in the area around Standon Green End as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Ralph Sadleir Middle School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Ware station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Standon Green End
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Standon Green End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why us?
- Experience in homes, commercial sites and hotels
- Old sealant always removed completely

Do you need external mastic in Standon Green End?
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
The most common problems we see are:
- Weathered mastic that no longer stretches
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
Homes close to St Mary's include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

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.
If you are set on DIY, put the effort into 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.
