Mastic sealing for Temple Dinsley sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Temple Dinsley are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Preparing the site
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open

Advice
About our mastic sealing in Temple Dinsley
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. If you have cracked, hardened mastic round windows on a block and open joints in brickwork or panels, 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: in Temple Dinsley, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Temple Dinsley, we group work so one trip covers it. Send photos of the frames and joints and we will give a fixed quote.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Why it’s worth doing now in Temple Dinsley
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. One visit to deal with every failing joint makes more sense than several trips to a place like Temple Dinsley. Photos of every joint help us quote for the whole job.
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.

How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- Location, for remote and island sites
- How much existing material needs removing
- Backing rod, priming and other preparation
- The total length or number of joints
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Any specification or named product
- When you need the work done
- Where the site is, with the postcode
- Clear photos of the problem areas
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email us if you’d rather talk the job through.
What we are called out for in Temple Dinsley
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Typical triggers for a call:
- Movement joints with sealant missing
- Draught complaints from residents or tenants
- Water getting in round frames after rain
- Communal area joints that look neglected
Blocks of flats and mixed-use buildings often cluster around stations such as Stevenage station, 2.9 miles to the east of Temple Dinsley, and their window and balcony mastic tends to age at the same rate across a building.

- How long is the guarantee, and what does it include?
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Materials that need asbestos testing before work
- Frames that are rotten, warped or broken
- Broken glass or failed sealed units
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
What we seal

Mastic sealing around Temple Dinsley: what changes locally
The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Temple Dinsley lies roughly 29 miles out from central London. 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.
Trustees of buildings like Church of St Martin can bring frame and external mastic into a planned maintenance list. Schools and community buildings such as Preston Primary School need frame and external mastic kept sound like any building.

Questions we are asked in Temple Dinsley
Is Temple Dinsley too small for you to travel to?
No. Places such as Temple Dinsley are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is Horizon Technology Park, near Temple Dinsley, within your area?
Yes. Our area takes in Temple Dinsley and its surroundings, with estates and business parks such as Horizon Technology Park included. Photos and a short description are enough for a first look.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
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.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
