External & façade joints in Brentwood, Essex
We cover Brentwood for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
External mastic in Brentwood, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. Common call-outs are for plants rooting in failed movement joints and rain getting behind render or cladding at a joint, on joints between brick and frames, copings & trims and concrete & block.
Brentwood mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
You get a one-year guarantee, the same in Brentwood as everywhere else we work.
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What we do, step by step
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours to a few days, depending on the length of joint and the access. Parking in a town like Brentwood is generally straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work

How we quote for external mastic
We quote each job individually. This is what makes a difference:
- The product the joint needs
- The number and length of the joints
- How easy the joints are to reach
- When we can work, for business premises

What to tell us for a quote
To make quoting easier, let us know:
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- If someone has resealed it before

FAQs for Brentwood
Is Brentwood in your area for external mastic?
Yes, Brentwood is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Brentwood station?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. There’s a wide choice of exterior colours.
Why act early in Brentwood
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a family home in Brentwood, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Homes, businesses and hotels
- Anti-fungal sanitary silicone in wet areas
- We agree the colour with you first
- We’re fully insured

What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Damp that isn’t coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Render that is blown, hollow or coming away
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Render & cladding joints
- Façade panels
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Copings & trims
Brentwood buildings and the weather
Historic houses like Ingatestone Hall (about 4.4 miles north-east) are a reminder that the area around Brentwood has older buildings as well as new. In older buildings, 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.
If you live in an older home near Church of St Thomas of Canterbury, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Brentwood station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Signs you need external mastic in Brentwood
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Keep an eye out for any of the following:
- Old sealant gone brittle and cracked
- Failed seals between different materials
- Sealant that has lost its bond to the brick or render
- Rigid filler in a joint that should flex
For site and facilities teams at buildings such as Becket Keys Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
