Modernising a brick house does not automatically mean hiding the brick. The strongest result usually starts with an honest assessment: decide whether the masonry is sound and worth celebrating, identify moisture and mortar problems, then choose the least destructive finish that delivers the appearance and maintenance level you want.
Face brick can be cleaned, repaired and framed by contemporary colours. Uneven brick may suit a breathable wash or mineral coating. Render can deliberately change the architecture, while paint offers a dramatic colour shift but creates an ongoing repainting cycle. None of those treatments should be selected from a photograph alone.
Begin with the condition of the brickwork
Walk around the house after dry weather and again after rain. Photograph every elevation in even daylight. Note cracked or missing mortar, powdering brick faces, white salt deposits, moss, failed sealants, blocked weepholes, staining below gutters and places where garden soil or paving sits high against the wall.
Moisture comes before colour because a coating can disguise symptoms without stopping the source. Leaking downpipes, overflowing gutters, failed flashings, poor surface drainage and bridged damp-proof courses can keep masonry wet. Heritage Victoria’s detailed guidance on salt attack and rising damp explains that dampness and soluble salts interact to damage brick and mortar, particularly in older construction. It is technical guidance rather than a diagnosis for an individual house.
For more detail on this part of the project, see Rising Damp in Older Homes: Diagnosis and Treatment Options.
Look closely at the mortar as well as the bricks. Mortar joints are part of the wall’s weathering system, not decorative lines. A hard, dense patch beside softer historic bricks can concentrate deterioration in the brick edges. Wide cracks, stepped cracks, bulging walls or continuing movement call for an appropriately qualified building practitioner or structural engineer before cosmetic work. The broader structural renovation guide explains why cracks must be interpreted in context.
Create a written condition map
- Mark damp, salt, biological growth and rust staining separately.
- Record damaged bricks, open joints and previous incompatible repairs.
- Identify different brick batches, additions and filled openings.
- Check sills, lintels, flashings, vents and movement joints.
- Note exposure: strong sun, driving rain, coastal salts and shaded walls.
This map helps separate maintenance from style. It also prevents a renderer or painter from pricing a smooth finish while excluding the repairs needed beneath it.
Option 1: retain and clean the brick
Keeping face brick is often the lowest-intervention approach when the masonry is attractive and sound. Cleaning can lift soot, biological staining and old construction residue, but the method must match the brick, mortar and contaminant. Aggressive pressure, harsh acid or abrasive blasting can erode fired faces, open pores, discolour mortar and drive water deeper into a wall.
Start with a small trial in an inconspicuous area. Record the product, dilution, dwell time, agitation, rinse method and final appearance after the wall has dried. Heritage Victoria provides current links to masonry cleaning and conservation guidance and advises owners of registered places to obtain approval before making changes. Even an unlisted house may sit in a local heritage overlay, so check the property rather than assuming the controls from its age.
Cleaning will not make every brick identical. Variations, firing marks and repairs are often part of the building’s character. If the real objective is uniform colour, recognise that cleaning and coating answer different questions.
Option 2: repair and repoint the joints
Repointing removes deteriorated outer mortar and replaces it with a compatible new mix. Tuckpointing is a specialised decorative finish that creates a fine, regular joint appearance; it is not simply another name for filling gaps. Either treatment can sharpen an elevation, but poor cutting-out or an incompatible mortar can permanently damage brick arrises.
For older masonry, match performance before matching colour. The Heritage Council of Victoria’s guide to repointing mortar joints explains the role of lime mortars in older Australian brick and stone buildings. A modern high-cement mix should not be selected merely because it appears stronger. A conservation architect, heritage consultant or experienced masonry specialist can specify a trial mix where significance or soft bricks are involved.
Repointing works best when failed joints are localised or when the brick deserves to remain exposed. It does not solve structural movement, active damp or decayed bricks. Those causes need their own repair scope first.
Option 3: use a wash or mineral coating
Limewash and compatible mineral coatings can soften strong brick colour while retaining some texture and variation. Depending on the system, the finish may weather gradually instead of peeling like a film-forming paint. The visual effect ranges from translucent and mottled to relatively opaque, so full-size samples matter.
“Breathable” is not a complete specification. Ask the supplier to confirm substrate preparation, vapour behaviour, primer, coat build, curing, exposure limits and compatibility with existing sealers. A wall previously treated with silicone, acrylic paint or an unknown water repellent may not accept a mineral system evenly. Salt contamination and persistent damp can still cause failure.
This option suits owners who want a lighter, quieter façade but still value masonry texture. It also creates a new finish that will age and need maintenance. Keep product data, colour codes and trial records for future repairs.
Option 4: paint the brick
Paint produces the clearest transformation and can visually unite mixed brickwork, patched openings or an extension. It is also difficult to reverse without risk of surface damage. Once painted, the façade becomes part of a repainting program: joints, cracks, chalking, peeling and sealants must be maintained before water enters behind the coating.
Do not paint damp, salty or unstable masonry. Specify a complete system for the actual substrate and exposure, including cleaning, repairs, primer and compatible topcoats. Deep joints, rough bricks and high walls require more labour and material than a flat rendered wall. The exterior painting cost guide helps explain access, preparation and scope variables without treating paint as a simple rate per square metre.
Colour samples should cover several bricks and mortar joints, not a postcard-sized patch. View them morning, afternoon and under overcast skies. Warm off-white can read stark in strong sun; very dark colours can emphasise dust and heat exposure. Confirm the coating manufacturer’s restrictions before selecting a deep colour.
Option 5: render selected or complete walls
Render can give a brick house a deliberately new architectural language, correct visual inconsistency and create broad surfaces for colour. It can also obscure workmanship, crack where substrates move and trap moisture if the system is poorly matched or detailed. Render is a system of preparation, reinforcement where specified, base coats, finish coats, joints, flashings and edge details—not just a final texture.
Before rendering, determine whether cracks are stable, whether movement joints need to continue through the finish and how sills, weepholes, damp-proof courses and wall bases remain functional. The finish should terminate cleanly above paving and garden levels. Changes around windows may affect flashings and reveal depth.
Full render is not the only option. Rendering a dated addition, porch blade or damaged secondary elevation while retaining good original brick can create a more credible composition. The next step is to plan those elements as one elevation, which is covered in the house façade renovation guide.
Compare the finish options before committing
| Approach | Best suited to | Main limitation | Future obligation |
|---|---|---|---|
| Clean and retain | Sound, attractive face brick | Cannot hide inherent colour variation or poor repairs | Maintain joints, drainage and local stains |
| Repoint or tuckpoint | Deteriorated joints or character masonry | Specialist skill and compatibility are critical | Monitor movement and weathering |
| Limewash or mineral coating | A softer colour change with visible texture | Substrate and previous coatings may limit adhesion | Accept weathering and refresh as specified |
| Paint | A strong, uniform colour transformation | Difficult reversal and possible peeling | Inspect and repaint on a recurring cycle |
| Render | A substantial change of style or mixed masonry | Can crack or conceal moisture problems | Maintain coating, joints and edge details |
Modernise everything around the brick
A tired brick house may need very little work to the brick itself. Old aluminium windows, a weak front door, cluttered security screens, faded gutters, mismatched external lights and uncontrolled planting can make otherwise handsome masonry feel dated. Test a coordinated package before reaching for paint.
Roofline and rainwater goods
Roof tiles, metal roofing, fascia, gutters and downpipes form a large colour block. Repair leaks and overflow first, then reduce the palette to two or three related tones. Moving or resizing downpipes may require plumbing and stormwater advice; hiding them without providing access creates a maintenance problem.
Windows and openings
Recolouring sound frames may be enough. Replacement windows can improve operation, weather seals and thermal performance, but altered openings, lintels and wall flashings make the work more than decoration. The Australian Government’s renovation guidance recommends using renovation access to improve windows, insulation and shading for the climate.
Entry and porch
Create a clear path to the door with one focal colour, legible numbers, useful lighting and shelter that belongs to the house. A new canopy or enlarged opening may require design and approval checks. Scale the door, steps and planting to the elevation rather than adding unrelated “feature” products.
Landscape and boundary
Green foliage, gravel, restrained paving and a simple fence can make red, brown or cream brick look intentional. Keep irrigation and soil away from weepholes and wall bases. If the yard also needs functional work, plan it through the budget backyard renovation guide so drainage and access precede planting.
Check heritage and approval constraints
Age alone does not determine heritage status. Check the title, local planning maps, council heritage overlay or conservation-area controls and any state listing. Painting previously unpainted brick, changing windows, removing chimneys, adding render or altering a front fence can affect significant fabric or streetscape character.
Ask the responsible authority what can be maintained without approval and what needs consent. Obtain the answer in writing and make samples part of the approved documentation where required. Heritage Victoria’s guidance is a Victorian example; every state, territory and council has its own framework.
Test the design against the type of house
A finish that suits one brick home can flatten another. On an interwar bungalow, the depth of a porch, expressed chimney and patterned brickwork may carry most of the character; painting all of it one colour can erase that hierarchy. On a plain postwar brick veneer, retaining the main brick while simplifying rails, roof trim and planting may be enough. A later project with several mismatched additions may benefit from coating selected walls to make the original volume legible.
Draw three quick elevation options before deciding. The first retains all sound brick and changes only surrounding elements. The second coats a limited recess, addition or entry. The third changes the full wall finish. Compare each option from the street and close to the entry, then ask what physical work is required to achieve it. A restrained scheme that uses existing fabric generally carries less irreversible risk than a complete finish change.
Neighbouring houses should inform, not dictate, the proposal. Repeating the street’s roof pitches, setbacks or landscape rhythm can help a contemporary update belong without copying historic details. On a corner site, side walls and fences are part of the public composition too.
Specify samples that reveal technical risk
A sample is useful only when it reproduces the intended process. For cleaning, include an untreated control and test the gentlest method first. For repointing, show the depth of removal, mortar colour, aggregate, joint profile and finished texture. For a wash, paint or render, prepare enough area to include brick faces, joints, an edge and a repaired patch.
Ask the person proposing the system to document:
- how existing coatings, sealers and contaminants will be identified;
- the required substrate moisture and weather conditions;
- which cracks and joints remain visible or continue through the finish;
- how sills, vents, flashings and weepholes stay operational;
- where the finish starts and stops at wall bases and adjoining materials; and
- the cleaning, touch-up and recoating method expected later.
Leave samples through rain and several weeks of changing light where the program permits. Fresh render and wet coatings can look substantially different once cured. Approve the documented dry result, not the colour seen immediately after application.
Plan for the maintenance you are accepting
Retained face brick generally asks for local joint, sealant and water-management maintenance rather than wholesale recoating. Painted or rendered walls add a continuous finish that must be inspected for cracking, chalking, impact and loss of adhesion. Washes and mineral systems may weather in a way that is visually acceptable but still need planned renewal.
Create a simple elevation record at handover. Include dated photographs, product names, batch and colour references, preparation notes, sample locations, mortar recipe where relevant, warranties and safe cleaning instructions. Record concealed flashings and repaired cracks before they are covered. This information prevents a future owner or maintenance contractor from applying an incompatible patch because the original system is unknown.
Inspect after major storms and whenever gutters overflow or landscaping changes. Early attention to one failed sealant joint or blocked outlet is usually less disruptive than repairing a saturated wall behind a flawless-looking coating.
Sequence the work so the finish lasts
- Confirm planning, heritage and owners-corporation constraints.
- Inspect structure, moisture, salts, mortar and hazardous materials.
- Repair roof drainage, flashings, ground levels and active movement.
- Prepare large samples of cleaning, mortar and finish options.
- Coordinate windows, entry, services, lighting and landscaping.
- Complete masonry repairs before applying a compatible finish.
- Record products, colours, warranties and maintenance instructions.
If funds are limited, prioritise dry walls, sound joints, safe access and a coherent entry. Cosmetic work can then be staged using the principles in the cosmetic renovation guide. A modern brick house is not defined by whether the bricks are red, white or rendered; it is defined by a sound envelope, disciplined composition and materials that will age predictably.
