What affects the quote in Hook Green
You’ll get a clear quote before work begins. It’s based on:
- The number and length of the joints
- Any working-time requirements on site
- Access and height
- The product the joint needs
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
To make quoting easier, please include:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
How we handle external mastic in Hook Green
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We are often asked to deal with sealant that has lost its bond to the brick or render and joints with sealant missing in places, on concrete & block, joints between brick and frames and façade panels.
Somewhere as small as Hook Green, homes and farm buildings often face open ground, 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

FAQs for Hook Green
Is Hook Green within the area you cover?
Yes. Hook Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Longfield station?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Is it worth trying it myself?
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.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so it doesn’t stand out.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Hook Green and across Kent. Several sites can go on one quote, and we are fully insured.
If you manage several properties in or around Hook Green, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.
How to look after the new joints
So the new joints stay in good condition:
- Keep soil, plants and ivy away from the joints
- Wash walls gently around the sealant
- Check external joints each spring
- Point out the joints to other trades
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
What we cannot put right
To be straight with you, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.

What else we do in Hook Green
Hook Green buildings and the weather
With historic houses such as Cobham College (about 3.9 miles south-east) nearby, there’s older building stock in the area around Hook Green 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Sedley's Church of England Voluntary Aided Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What we are called out for in Hook Green
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
If you can see any of these, it’s time to have the joints looked at:
- Hard, crazed mastic that has stopped moving
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Sealant pulling away from one side of the joint
Letting a property close to Longfield station? Then split movement joints are easy to miss on a rental until damp shows inside.

- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
