Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Make it easy for occupiers to report draughts
- Reduce knocks to communal area joints
- Start inspections with the most exposed faces
- Group repairs into a planned programme
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Mastic sealing in Dumpford, done properly
For blocks and buildings in Dumpford and across West Sussex, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. We work on balcony and threshold joints, window and door perimeters on blocks and communal entrances and stairwells, and what we are called in for most is brittle perimeter mastic across a building and movement joints with sealant missing. A specialist sealant contractor works differently from a general builder: on jobs in Dumpford, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Dumpford tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or use the quote form and we will arrange a return visit.

Questions about Dumpford
Will you take on work at estates like Midhurst Business Centre, close to Dumpford?
Yes, sites like Midhurst Business Centre are within our area, along with the rest of Dumpford. A few photographs and the unit address let us price the work.
We manage a building near Liss station. Can you help?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you need mastic sealing in Dumpford?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Site and facilities staff are often the first to spot these:
- Damaged joints in communal entrances and corridors
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
- Draught complaints from residents or tenants
Property owners at sites such as Midhurst Business Centre, 3 miles to the east of Dumpford, can have mastic renewed between lettings.

Add it to your enquiry and we will build it into the plan.

What sets the cost
Before we quote, we look at:
- The site’s rules and procedures
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Travel to remote or island sites
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Sending details for a quote
However big the job, these details speed things up:
- Any dates the work must fit around
- Anything awkward about access or site hours
- Any specification or named product
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Planned mastic for Dumpford portfolios
Rainfall across the South East, Dumpford included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. At about 47 miles from central London, Dumpford is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
Buildings close to stations like Liss station, 4.9 miles to the north-west of Dumpford, are often flats over shops, with frame mastic to keep sound. Older community buildings, St George's Church among them, often have frames of mixed ages whose mastic varies.

Why it’s worth doing now in Dumpford
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. For buildings around smaller places like Dumpford, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
