Common questions from Fernham clients
Do you take on block-wide or estate-wide mastic work in Fernham?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we’ll give a fixed quote.
Is Faringdon Business Park, near Fernham, within your area?
Yes. Estates, retail parks and business parks around Fernham, Faringdon Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Mastic sealing in Fernham
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you have damaged joints in communal entrances and corridors and draughts at frames across a block, we can help. Most enquiries from Fernham 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.
For owners with a single building near Fernham, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

For owners and agents in Fernham
Rainfall across the South East, Fernham included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 64 miles from Fernham. 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.
Older buildings near Fernham, from historic houses such as Buscot Park (to the north-west of Fernham) to more modest stock, need compatible products when frames are resealed. Trustees of buildings like Church of St John can bring frame and external mastic into a planned maintenance list. For owners of several units at places like Faringdon Business Park, 1.4 miles to the north-west of Fernham, one programme can deal with frame and external mastic across the lot.

Different surfaces, different methods
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Check sealant joints during planned building inspections
- Group repairs into a planned programme
- Keep a record of when each building was resealed
- Check the asbestos register before any old mastic is disturbed
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Frames that are rotten, warped or broken
Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Leave it or put it right?
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Older rural buildings around Fernham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
