Mastic sealing across Harcourt Hill
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Failed window or door frames, which need a window contractor
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
- Communal kitchens and washrooms
Mastic sealing for commercial buildings in Harcourt Hill
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. The enquiries we see most involve patchy repairs in mismatched sealant and damp patches beside frames, on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Harcourt Hill, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Harcourt Hill, we group work so one trip covers it. Photos of each elevation help us quote accurately.
Our workmanship is guaranteed for 12 months, in Harcourt Hill as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sets the cost
Each job is priced on its own details. The main factors are:
- Whether the work must be split into stages
- Backing rod, priming and other preparation
- Whether old sealant has to be cut out first
- Access and working height
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. 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
- Specification clauses that apply
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Share your contractor requirements early
- Plan resealing building by building rather than complaint by complaint
- Log resealing dates block by block
- Reduce knocks to communal area joints
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
Looking after buildings in and around Harcourt Hill

Student accommodation around universities such as University of Oxford, 2 miles north-east of Harcourt Hill, is normally managed block by block, which suits a planned mastic programme.

When to bring in a specialist
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. Getting these wrong usually costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
