Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Frames, entrances and external joints in Patching
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. There are two care or nursing homes within about 2 miles of Patching. Care home owners need frame and external mastic kept sound without unsettling residents.
For agents with blocks near Goring-By-Sea station (2.3 miles south-east of Patching), a block-wide mastic programme deals with frames, balconies and entrances in one go. Trustees of buildings like The Parish Church of St John the Divine can bring frame and external mastic into a planned maintenance list. Historic properties like Ecclesden Manor, 1.5 miles to the south-west of Patching, show the age of some local stock, where frame mastic must suit soft brick or stone.

How we handle mastic sealing in Patching
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. The enquiries we see most involve no planned programme for sealant and a mix of products and colours from past repairs, on balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells. For commercial sealant work in Patching, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For buildings around smaller places like Patching, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Leaks from above rather than through a joint
- Misted or failed double-glazed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Surfaces we seal
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
Common questions from Patching clients
Can you work in a care home near Patching with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Can you quote for a block close to Goring-By-Sea station?
Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
For managing agents and facilities managers
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Quoting for work in Patching
What shapes the price:
- Access and working height
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- Working within restricted access windows
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- What the building is and how it’s used
- Your programme or deadline
- Any specification or named product
- Asbestos survey details if the building is older
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, phone 01277 525 020 or email the details over.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Surface by surface
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes one or more days per building, depending on the joint lengths and the access.
