House rendering, render repair and exterior masonry painting in Bristol
Render does two jobs at once. It changes how a building looks, and it acts as the weather coat protecting the masonry behind it. When render is right, both jobs get done for decades. When it is wrong, it can trap moisture in the wall and cause more harm than bare brick ever would.
TB Rooflines works across new render, render repair and exterior masonry painting. Bristol covers a wide spread of building ages, from Georgian and Victorian terraces in Clifton, Redland and Totterdown through to interwar semis and modern estates further out. Roof coverings vary just as much, so the right answer on one street is often wrong two roads away.
Render systems and which suits your wall
The choice of system matters more than the colour, and it depends heavily on what your wall is built from.
Sand and cement is the traditional system, usually painted after curing. It is cost effective and repairable, and it remains a sound choice on solid masonry in good condition. It is relatively rigid, so it can crack with movement, and it needs a breathable masonry paint rather than an impermeable one.
Silicone render is applied over a basecoat and mesh, and it is the common modern specification. It is flexible, highly water repellent while still allowing vapour out, and self cleaning to a useful degree. It comes coloured through, so there is no painting cycle.
Through colour polymer and acrylic renders sit between the two on cost and share the no repainting benefit.
Lime render is the correct answer on older solid wall property built to breathe, and on many listed and conservation buildings. Putting cement render on a soft stone or lime built wall is one of the more damaging things you can do to it, because it traps moisture that the wall was designed to release.
In parts of Bristol with older or protected building stock, the system is not purely a preference. Conservation area status or listed building consent can determine what is permitted, and that gets checked before anything is specified.

Preparation, breathability and repainting cycles
Most render failures trace back to preparation rather than the material. A render is only as good as what it is applied to.
Preparation on a typical job covers:
- Removing loose, hollow or blown render back to a sound edge, checking by tapping rather than by eye
- Identifying and fixing the water source first, whether that is a leaking gutter, a failed sill or a bridged damp proof course
- Checking the render will finish at least 150mm above ground level, so it does not bridge the damp proof course and draw ground water into the wall
- Beading at corners, stop ends and around openings
- Mesh reinforcement in the basecoat where movement or mixed substrates are a factor
- Masking and protecting windows, doors and ground
On exterior painting, the same logic applies. A breathable masonry paint lets the wall release moisture. A cheap impermeable coating seals it in, and the usual result is blistering within a few years plus a damp problem inside. Expect roughly ten to fifteen years from a good masonry paint system on sound render, and considerably less if the surface was not prepared properly. Silicone and through colour renders avoid the cycle entirely, which is a large part of their appeal.
Why choose TB Rooflines for rendering & exterior painting in Bristol?

- System matched to the wall, including lime where a solid wall needs to breathe
- The water source found and fixed before any render goes on
- Render finished clear of the damp proof course rather than bridging it
- Breathable masonry paint, so the wall can still release moisture
