Mastic sealing for commercial buildings in Baker's Cross
Treatment starts with a proper look: 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. We work on balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks, and the failures we’re asked to look at most are patchy repairs in mismatched sealant and failed external movement joints. Whoever orders the work in Baker's Cross, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Baker's Cross, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Baker's Cross: questions and answers
Can one quote cover a number of our buildings near Baker's Cross?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is a smaller place like Baker's Cross outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
Block-wide mastic in Baker's Cross
Baker's Cross lies roughly 39 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Baker's Cross sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you own or manage units on a site such as Hartley Dyke Business Centre, 1.4 miles to the south-west of Baker's Cross, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like Church of St Dunstan can bring frame and external mastic into a planned maintenance list. Schools and community buildings such as Cranbrook School need frame and external mastic kept sound like any building.
Baker's Cross is about 9 miles south-east of Paddock Wood, in Kent. If you are looking for mastic sealing in Baker's Cross, we can help. Across Kent, 931 places are covered, including Baker's Cross. We also cover Brighton, some 34 miles away.
Postcode districts covered here: TN17 and TN18. If your site is on Dorothy Avenue, Brickenden Road and Doctor Hope's Road or close by, send details and we will quote for mastic joints. Close to Baker's Cross, our area also takes in Cranbrook (1 mile west), Coursehorn (1 mile east), Swattenden (1 mile south-west), Hartley (2 miles south-west) and Benenden (2 miles south-east). A short drive away, we cover Maidstone (12 miles north), Ashford (14 miles east), Royal Tunbridge Wells (12 miles west), Tonbridge (14 miles north-west), Kings Hill (14 miles north-west) and Foley Park (13 miles north).
Near you in Baker's Cross

Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Aftercare for building managers
To get the most from the new sealant:
- Plan resealing building by building rather than complaint by complaint
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Prioritise elevations facing the weather
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Baker's Cross. Send photos of each area and we’ll quote for the lot.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Cost factors for mastic joints
A fixed quote reflects the actual work. It takes account of:
- Which sealant the job calls for
- Backing rod, priming and other preparation
- Working within restricted access windows
- Induction, permit and paperwork requirements
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- Approximate linear metres or a joint schedule
- Any specification or named product
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or use the quote form with what you know.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Substrate edges that need repairing first
- Water coming in from the roof or rainwater goods
- Broken glass or failed sealed units
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.
What we seal
- Window and door perimeters on blocks
- Balcony and threshold joints
