Many villas in Riyadh’s older neighbourhoods were built on solid frames, but years of heat, damp and patch repairs have taken their toll on walls, roofs and services. The real question for an owner is not just whether to renovate, but what to tackle first and what is worth keeping. This guide covers how to assess an older villa before any demolition, how to decide between repair and replacement, and how to phase the work sensibly.
Start with an inspection, not a hammer
The most expensive renovation mistakes happen when work starts before anyone understands the building. Tiles get lifted and relaid, and months later it turns out damp was rising from the foundations all along. Or a ceiling is repainted and rust stains bleed through because the reinforcement inside is corroding.
Good renovation reverses that order: understand the causes, fix the causes, then finish. So the first step should be a site visit with an engineer, not a quick quote over the phone.
What a proper assessment covers
The concrete frame
The frame decides whether renovation is worthwhile at all. Look for:
- Cracks in columns, beams and slabs. Hairline cracks in plaster are usually cosmetic. Diagonal or wide cracks in concrete members need an engineer’s opinion.
- Spalling and exposed steel. When the concrete cover (the outer layer that protects the reinforcement) falls away and rusty bars show, moisture has reached inside the member.
- Settled floors. Sunken ground-floor tiles can point to poorly compacted fill underneath, or a drainage leak that has washed soil away.
Damp and insulation
Damp is the main enemy of older villas. Watch for white salt deposits low on walls, flaking paint near the floor, and stains on ceilings under the roof or below bathrooms. Roof insulation and waterproofing are often past their useful life.
Electrics and plumbing
Older wiring is rarely sized for today’s air conditioning and kitchen loads. Old metal pipes can be corroded inside even when they look fine from outside, so a pressure test tells you more than a visual check.
Termites
Damaged door frames or thin mud tunnels on walls are signs of termites. If they are present, treatment must come before any new finishes.
Keep or replace? A practical guide
The rule of thumb: keep what can be repaired with confidence; replace what hides a recurring problem.
| Element | Keep when | Replace when |
|---|---|---|
| Concrete frame | Sound, or with local damage that can be repaired | Damage is widespread and the engineer judges repair not viable |
| Blockwork walls | Stable, tied to columns, no active cracks | Cracked, detached from the frame or damp-damaged |
| Plaster | Firm, sounds solid when tapped | Hollow, crumbling or salt-saturated |
| Wiring | Relatively recent and adequately sized | Old, exposed or overloaded |
| Water and drainage pipes | Pass a pressure test | Corroded or leaking repeatedly |
| Floor tiles | Firm, level, no hollow sound | Cracked, sunken or damp underneath |
| Roof waterproofing | Intact with no leaks below | Expired or with stains below |
Keeping something does not mean ignoring it. A wall you keep may still need its plaster stripped and redone.
Repairing damaged concrete
Rusty reinforcement is never fixed by plastering over it. In general terms the repair is: break out loose concrete back to sound material, clean the steel and check whether it has lost section, apply a protective coating and add bars if the engineer requires, rebuild the section with approved concrete repair materials, and deal with the moisture source so the rust does not return. Larger damage may call for strengthening, which is an engineering decision based on inspection. See Reinforced Concrete Works for the scope.
Phasing the work
Renovation follows the same logic as new build: from the deepest layer to the visible one, each stage checked before the next covers it.
- Strip-out and discovery. Remove failed finishes while protecting what stays. Surprises appear here, so the contract should say how extra work is agreed before it is carried out.
- Structural repairs and protection. Concrete repairs, termite treatment with approved products, roof waterproofing and fixing damp at the source.
- Services. New electrical and plumbing runs as needed, with pressure tests before walls and floors are closed.
- Walls and plaster. Rebuild damaged blockwork, then plaster with mesh at concrete–block joints. Our plaster quality checklist explains what to look for.
- Floors and finishes. Screed and tiles, gypsum ceilings, paint, doors, kitchens and bathrooms. See Interior Finishing and Floor Levelling & Tiling.
From a bare soil floor to a finished bedroom
On our projects page you can see a room that started with an exposed soil floor and unfinished walls and ended as a finished bedroom. That kind of result does not start with tiles. It starts underneath: preparing and compacting the ground, treating it against termites, laying a moisture barrier and casting a concrete floor, then levelling and finishing. Tile straight onto the old ground and settlement and damp show up soon after.
Common mistakes
- Finishing over the problem. Painting a damp wall or tiling a sunken floor buys a few months at most.
- Doing the facade first. Structure, waterproofing and services come first; the facade finish can follow.
- Removing walls without an engineer. Some walls in older villas carry load or help stability.
- A vague contract. Renovation is full of unknowns; without itemised scope and a process for extras, disputes follow.
What drives renovation cost
Condition matters more than size: the extent of structural damage, how far damp has spread, whether services are fully or partly replaced, the finishing level you want, and whether the family stays in the house during the work. That is why an accurate figure needs a site visit, and why proposals should be compared item by item rather than on the total.
How Marafi approaches renovation
Every renovation starts with a site visit and inspection of the structure, damp and services, followed by a transparent itemised proposal by stage. We treat soil and damaged elements with approved materials, lay polyethylene sheet against moisture before new floor slabs, and follow the engineering drawings for anything that touches the structure. Our labourers, technicians, supervisors and engineers work to the highest safety standards, and you receive photos as each stage is completed. Learn more on Renovation & Rehabilitation and How we build. If you are weighing a full rebuild instead, read villa construction stages in Riyadh.
Quick checklist before you renovate
- Get a full engineering inspection before breaking anything.
- Fix damp, rust and termites before finishing.
- Decide keep or replace based on findings, not appearance.
- Work from the deepest layer outward: structure, waterproofing, services, finishes.
- Pressure-test pipes before closing walls and floors.
- Sign an itemised contract with a clear process for extra work.

Frequently asked questions
Should I renovate an old villa or demolish and rebuild?
It depends on the concrete frame. If the columns and slabs are sound or repairable, renovation is usually quicker and better value. If structural damage is widespread, an engineer decides after inspection whether repair makes sense.
What is the first step in renovating an older villa?
A full site inspection in which an engineer checks the structure, damp, electrics, plumbing and roof insulation. The findings become a prioritised scope of work before anything is demolished.
Do I need a permit to renovate my villa?
Work that touches the structure, changes the layout or alters the facade usually needs a permit through the Balady platform, while simple interior work may be treated differently. Procedures change, so check the official platform first.
How do I get an accurate cost for a renovation?
Through a site visit and inspection of the actual condition, followed by an itemised proposal by stage. Renovation cost depends far more on what the building reveals than on its floor area.
