Mastic sealing in Lee Gate
For blocks and buildings in Lee Gate and across Buckinghamshire, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you have failed external movement joints and water getting in round frames after rain, we can put it right, whatever the surface. Most enquiries from Lee Gate start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Lee Gate, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When to call us in Lee Gate
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
What tends to prompt an enquiry:
- Complaints coming in block by block
- A mix of products and colours from past repairs
- Draughts at frames across a block
- Damp patches beside frames
Student accommodation around universities such as Buckinghamshire New University, 4.7 miles south-east of Lee Gate, is normally managed block by block, which suits a planned mastic programme.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
- How they’ll work around occupants
- Will CSCS-carded applicators be on site?
When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Materials that need asbestos testing before work
- Failed window or door frames, which need a window contractor
- Glazing that needs replacing
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.
What we seal
- Window and door perimeters on blocks
- External wall and movement joints

Lee Gate: questions and answers
Is a smaller place like Lee Gate outside your area?
No. Places such as Lee Gate are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can you quote for a block close to Wendover station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you do block-wide mastic programmes?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What affects the price in Lee Gate
Each job is priced on its own details. The main factors are:
- Removal of failed or old sealant
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
Access can matter as much as the joints themselves: 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 to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Whether the building will be occupied during the work
- Clear photographs of the problem areas
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email the details over.
Mastic sealing in Lee Gate: the local picture
Rainfall across the South East, Lee Gate included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 31 miles from central London, Lee Gate is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
For owners of several units at places like Station Approach Business Park, 2.7 miles to the north-west of Lee Gate, one programme can deal with frame and external mastic across the lot. If your remit includes a building such as Lee Common Church of England School, frame and door mastic can be programmed for the holidays.
