External Mastic in Tattenhoe
We cover Tattenhoe for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Damp patches traced to an open external joint
- Hard, crazed mastic that has stopped moving
- Gaps where render, brick and frames meet
External mastic for homes and businesses in Tattenhoe
Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you have moss and dirt in joints with no sealant left and cracked joints where brick meets render or frames, we can help, whatever the surface.
Around Tattenhoe, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Common questions in Tattenhoe
I let a flat near Bletchley station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Tattenhoe?
Yes, Tattenhoe is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts from the range available.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we’ll do them. Tell us about the building and we’ll confirm what access is needed.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.
What affects the quote in Tattenhoe
Your quote is based on your job. We take into account:
- Any working-time requirements on site
- How many areas need sealing
- Any mould that needs treating
- The size of the job
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What we need to know
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- Any previous sealing or DIY work
- Whether it’s a home or a business
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or send us an email.
External mastic in Tattenhoe: local notes
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. With historic houses such as Bletchley Park (about 2.1 miles east) nearby, there’s older building stock in the area around Tattenhoe as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Giles Brook Primary School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as St Giles's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Tattenhoe is about 1 mile south-west of Furzton, in Milton Keynes. From the centre of Tattenhoe to the outskirts, we cover external mastic for every kind of property. Our area takes in 73 places across Milton Keynes, large and small. For nearby work, see our Oxford page.

Landmarks near Tattenhoe

The nearest railway station is Bletchley station, roughly 2.3 miles east of the centre. Nearby you’ll also find Hangmans Hill (2.2 miles south) and The Holley/Cornelius Collection (2 miles east). Green spaces nearby include Furzton Lake and Blue Lagoon Park.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right 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.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Point out the joints to other trades
- Ask before painting over external sealant
- Have failed joints looked at early
- Keep water from gutters off the wall
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint and spoil the finish.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
When to call us in Tattenhoe
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Keep an eye out for any of the following:
- Hard, crazed mastic that has stopped moving
- Brick movement joints where the sealant has split
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
Rented homes near Bletchley station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a job in Tattenhoe, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Mention any tricky access
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Why it’s worth doing now in Tattenhoe
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 Tattenhoe, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before any work starts.
