FAQs: Sellindge
Is Sellindge too small for you to travel to?
Not at all. Sellindge is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Will you take on work at estates like Evegate Business Park, close to Sellindge?
Yes. Our area takes in Sellindge and its surroundings, with estates and business parks such as Evegate Business Park included. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can you fit around our programme?
The programme sets the job. Tell us the sequence and we will plan applicators around it.
Can you clear a mastic snag list before handover?
Yes. We can work through a mastic snag list area by area before handover.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How we handle construction mastic in Sellindge
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We work on window and door perimeters, brick and block movement joints and cladding and panel joints, and the failures we are asked to look at most are missed perimeter joints on a new elevation and oversized or tapered gaps around new frames. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sellindge it comes down to the same thing: the right product in a properly prepared joint.
In the countryside around places like Sellindge, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Signs you need construction mastic in Sellindge
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
Any of the following is a good reason to get the joints checked over:
- Missed perimeter joints on a new elevation
- Caulk cracking where joints are moving more than expected
- A mastic package split between trades with no clear owner
- Oversized or tapered gaps around new frames
For a contractor working at a hospital such as William Harvey Hospital, 4.7 miles to the north-west of Sellindge, perimeter and facade sealing is planned around patients and deliveries.
What your quote should include
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Their public liability cover
- Will CSCS-carded applicators be on site?

When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Stick to the specified sealant rather than a generic substitute
- Share drawings and the specification as soon as possible
- Don’t schedule sealing before decorators and flooring are done
- Don’t force external sealing on a damp or frosty day
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Why act early in Sellindge
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple and a consistent finish. Converted and older buildings near places like Sellindge tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
