About our mastic sealing in Headington
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Most enquiries involve draughts at frames across a block and open joints in brickwork or panels, on balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks. Looking for mastic applicators who cover Headington? We have been sealing commercial buildings since 2005.
Places the size of Headington usually have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Signs you need mastic sealing in Headington
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Site and facilities staff are often the first to spot these:
- No planned programme for sealant
- The same joint failures repeated across a portfolio
- Damaged joints in communal entrances and corridors
- Water getting in round frames after rain
Landlords with units on estates such as Shotover Trading Estate (1.1 miles south-east of Headington) can bring frame, door and external mastic across several units into one programme.

Blocks and managed buildings in Headington
Headington sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 51 miles from Headington. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.
Student blocks close to universities like Oxford Brookes University (0.9 miles south-west of Headington) are easiest to work on between tenancies. Churches, halls and community buildings such as St Andrew's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If neighbouring businesses or buildings around Headington need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use

Why act early in Headington
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once and is simpler to manage and budget. For buildings in places like Headington, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

FAQs: Headington
We manage a building near Oxford station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Headington too small for you to travel to?
No. Places such as Headington are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
