Mastic sealing for commercial buildings in Frithsden
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Frithsden carry our 12-month guarantee. The enquiries we see most involve failed external movement joints and repeated reactive repairs to the same buildings, across balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells. Most enquiries from Frithsden start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Frithsden, 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Frithsden can sit alongside others in a wider programme.
Common problems we fix in Frithsden
Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
If one of these sounds familiar, it’s time for a closer look:
- No planned programme for sealant
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
- A mix of products and colours from past repairs
Churches, halls and community buildings such as Church of St Lawrence are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Before you book anyone

- Their approach to joint depth and backing
- The named product and why it was chosen
- What the guarantee covers, and for how long
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Substrate edges that need repairing first
- Misted or failed double-glazed units
If you are not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Frames, entrances and external joints in Frithsden
Frithsden is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. At about 27 miles from central London, Frithsden is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
Site managers at schools like Potten End CofE Primary School can fit frame mastic into the summer works. If you own or manage units on a site such as River Park Industrial Estate (2.2 miles west of Frithsden), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
Frithsden is about 2 miles north-east of Berkhamsted, in Hertfordshire. We send applicators to Frithsden for mastic joints. Frithsden is one of 371 places in Hertfordshire on our list for mastic joints. London is covered too, around 27 miles from Frithsden.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For work around Frithsden, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you

Why it’s worth doing now in Frithsden
Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Older rural buildings around Frithsden move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. Call for a quote.

Your questions answered
We manage a building near Berkhamsted station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Is a smaller place like Frithsden outside your area?
No. Places such as Frithsden are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
It depends on the scope, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Joint width, depth and condition
- The site’s rules and procedures
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Send us:
- Rough lengths or quantities, or drawings if you have them
- The type of building and who uses it
- Any specification or named product
- Asbestos survey details if the building is older
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or use the quote form.
