Mastic sealing for commercial buildings in Fern
For blocks and buildings in Fern and across Buckinghamshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. We work on shopfronts below residential blocks, balcony and threshold joints and external wall and movement joints, and the usual reasons a site gets in touch are cracked, hardened mastic round windows on a block and failed external movement joints. Most enquiries from Fern 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.
Around smaller places like Fern, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Around Fern, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- Colours confirmed for the specified product
- Work carried out by CSCS-carded applicators
- Coloured sealants to suit the setting, where available
- 12-month guarantee on workmanship

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Masonry that has broken away beside the joint
- Materials that need asbestos testing before work
- Misted or failed double-glazed units
If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer.
Joints and surfaces we work on
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Balcony and threshold joints
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Jobs in and around smaller places like Fern are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Getting the site ready
- Share your working hours and any access restrictions
- Make sure the joints can be reached
- Share the asbestos register for older buildings

Common problems we fix in Fern
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Common reasons buildings call us in:
- No planned programme for sealant
- Estate-wide sealant that is simply worn out
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
For agents with blocks near Bourne End station, 1.1 miles south-east of Fern, a block-wide mastic programme deals with frames, balconies and entrances in one go.
What your quote should include
- Their public liability cover
- What the guarantee covers, and for how long
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
Quoting for work in Fern
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Any access equipment needed
- The product specified
- Joint width, depth and condition
- Whether old sealant has to be cut out first
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Send us:
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- The site address and postcode
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email a schedule or drawings.
For owners and agents in Fern
At about 28 miles from central London, Fern is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Older community buildings, Church of St John the Baptist among them, often have frames of mixed ages whose mastic varies. Schools and community buildings such as Little Marlow CofE School need frame and external mastic kept sound like any building.

FAQs: Fern
Is Fern too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you work for managing agents with blocks near Bourne End station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
