Mastic sealing in Crampmoor
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Different surfaces, different methods
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Mastic sealing in Crampmoor, done properly
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable throughout. If you have damaged joints in communal entrances and corridors and brittle perimeter mastic across a building, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Crampmoor, preparation and product choice get the time they need.
For owners with a single building near Crampmoor, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email the details over and we will arrange a return visit.

Doing it in-house
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

FAQs: Crampmoor
Is Crampmoor off your patch?
Not at all. Crampmoor is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you work in a care home in Crampmoor without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Why it’s worth doing now in Crampmoor
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Around Crampmoor, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
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.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Share your contractor requirements early
- Track which buildings were done and when
- Look at the sunniest and most exposed elevations first
- Check sealant joints during planned building inspections
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Crampmoor, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email a schedule or drawings.
Advice
Block-wide mastic in Crampmoor
Crampmoor sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Crampmoor lies roughly 68 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations.
If your remit includes a building such as Cupernham Infant School, frame and door mastic can be programmed for the holidays. Historic properties like Mottisfont Abbey, 4.4 miles north-west of Crampmoor, show the age of some local stock, where frame mastic must suit soft brick or stone. For agents with blocks near Romsey station, 1.8 miles to the south-west of Crampmoor, a block-wide mastic programme deals with frames, balconies and entrances in one go.
