50% upfront
After seven years in Phuket, I've learned exactly what it costs to renovate here, who to trust with your villa or condo, and what paperwork actually matters. Renovation costs vary wildly — sometimes 200–300% for the same job depending on where you hire and which materials you use. This guide is built on real prices, real contractors, and real mistakes I've seen expats make.
Can You Renovate as a Renter?
Most Thai lease agreements don't allow structural changes. But cosmetic improvements are usually fine with written permission.
Cosmetic vs. Structural
- Usually OK with permission: Painting, shelving, curtain rods, light fixture changes, flooring in existing rooms
- Usually NOT allowed: Knocking down walls, moving electrical/plumbing, adding rooms, pool work
- Always required: Written landlord approval, in English AND Thai
A common negotiating tool for long-term renters is to offer cosmetic improvements (fresh paint, new fixtures) in exchange for a longer lease. Many landlords prefer this to doing work themselves. Always photograph the property before and after — it protects you both.
Finding Thai Contractors in Phuket
The biggest renovation mistake expats make is cold-searching for contractors instead of using community recommendations. Quality varies wildly.
Where to Find Contractors
- Facebook groups (most reliable): Phuket Expats, Rawai/Nai Harn Expats, Bang Tao/Laguna Expats, Chalong Expats. Ask directly — people will give you names they've used.
- Word of mouth: Ask at your development office, ask neighbors, ask your property agent. Recommendations carry weight.
- Bilingual contractors: Common in Patong, Kamala, Bang Tao, Rawai. They charge a premium (20–30% more) but eliminate communication disasters.
- Contractor hubs: Chalong and Wichit have clusters of building suppliers and contractor networks. Easier to get 3 quotes.
Red Flags
- Contractor wants 70%+ upfront (50% max is normal)
- No written quote or measurements
- No photos or references of past work
- Doesn't ask questions about your specific needs
- Pushes expensive upgrades without understanding your budget
Always get three quotes — even the same contractor will give different prices on different days. Don't automatically pick the cheapest; compare scope, timelines, and materials carefully.

Building Permits & Bureaucracy
Phuket's permit system is simpler than many Thai provinces, but don't skip it for structural work. The consequences are serious.
What Requires a Permit?
- Required: Structural changes, new extensions, swimming pool construction, roof modifications, electrical system upgrades, plumbing system changes
- NOT required: Painting, interior flooring, fixtures (sinks, taps, light fittings), cabinet work, landscaping, garden furniture
The Permit Process
- Apply to local OrBorTor (Subdistrict Administrative Office) — Chalong, Rawai, Patong, etc.
- Timeline: 2–6 weeks depending on workload and completeness of application
- Required: Building plans (architect or contractor can arrange), site photos, property deed or lease copy
- Cost: Usually ฿500–฿3,000 depending on project scope
- If you don't own the property: The owner must apply, not you as renter
Many expats ask: "Can I just renovate without a permit?" The risk is high. If your landlord, neighbor, or the OrBorTor discovers unpermitted structural work, you're liable for fines, forced removal of work, and legal complications. It's genuinely not worth it.
Common Renovation Mistakes in Phuket's Climate
Phuket's heat, humidity, and salt air kill bad materials fast. Here's what to avoid:
- Using MDF for cabinets or built-ins: It swells instantly in 70%+ humidity. Use marine plywood or solid hardwood instead. MDF is cheaper — usually a false economy here.
- Cheap paint, especially exterior: UV destroys budget paint in 12 months. Use Thai brands like NCS or TOA specifically rated for tropical exterior use. Worth the extra cost.
- Poor waterproofing in wet rooms: Mold appears fast. Ensure concrete walls are sealed before tiling, use waterproof membranes behind showers, and plan ventilation.
- Inadequate ventilation: Humidity traps moisture. Ensure bathrooms have extractors, kitchens have range hoods, and bedrooms have cross-ventilation or AC.
- Skipping anti-termite treatment: Before laying new flooring, treat the subfloor. Termites are serious in Phuket. Use licensed pest control contractors.
- Cheap outdoor electrical work: Salt air corrodes connections. Outdoor outlets MUST have ground fault protection (safety switches). Never DIY this — use a licensed PEA electrician.
Materials & Suppliers in Phuket
Knowing where to get reliable materials saves money and stress. Here are the real places people use:
- HomePro, Chao Fa Road, Chalong: Best selection for paint, fixtures, power tools, small hardware. Reliable stock. Staff speak English.
- Global House, Wichit: Bulk building materials, larger quantities, better prices for big orders.
- Ban Khai village, Rawai: Custom wood furniture and joinery. Craftspeople work from small factories here. Excellent for built-ins, custom doors, wooden stairs.
- Index Living Mall, Chao Fa West: Tiles, bathroom fixtures, kitchen fittings. Good price competition. Check spec carefully on online purchases.
- Lazada/Shopee: Cheap fixtures, fittings, decorative items. Fast delivery. Check reviews carefully — spec variations are common.
- Rimping Supermarket: Not useful for hardware — focus on groceries. Don't waste time here for building supplies.
6 Insider Tips
- Photograph everything before work starts. Document every room in detail (video walkthrough is ideal). Protects you both if disputes arise.
- Pay in stages tied to milestones. Never pay 100% upfront. Common structure: 50% to start, 30% at mid-point, 20% on completion. Protects your leverage.
- Budget 20% contingency. Materials are always needed, humidity causes delays, hidden issues (rotten wood, termites) are common in older homes.
- Avoid rainy season (June–October). Materials are harder to move, humidity affects paint application, workers are slower. March–May is ideal.
- Ask your property management company. Many developments maintain approved contractor lists. They vet for reliability. Worth using if available.
- PEA electrical work must be licensed. Don't let contractors "handle" electrical work unofficially. Use a licensed PEA electrician. It's required by law and safer.
Frequently Asked Questions
No. Cosmetic work like painting doesn't require a permit from the OrBorTor. Only structural changes, new construction, and pool work need permits. If you're renting, still check your lease and get written permission from your landlord for any work, including painting.
A full bathroom retile and suite replacement typically takes 2–4 weeks, depending on the size, contractor availability, and any hidden issues (rotten wood, mold). Simple fixture replacement is 3–5 days. Always add a buffer for unexpected delays — contractors often underestimate in Phuket.
Yes. Thai lease agreements typically restrict structural changes. Always get written permission before any work — this protects both you and your landlord. Cosmetic work is usually allowed with permission. Document everything in writing in both English and Thai to avoid disputes later.
Quality varies hugely. Use recommendations from the expat community (Facebook groups like Phuket Expats or Rawai/Nai Harn Expats) rather than cold searches. Always check references and photos of past work. Bilingual contractors cost more but eliminate communication disasters. Get three quotes — prices vary 200–300% for the same job.
Ideally March–May (dry season, before the monsoon begins in June). Rainy season (June–October) makes materials harder to move, humidity affects paint adhesion and drying, and contractors work slower. If you're in a time crunch, accept that rainy season work will be slower and more expensive.
