How to find a reliable contractor for house construction: 7 selection criteria
Choosing a contractor is one of the most important decisions when building a private house. A mistake at this stage can cost hundreds of thousands and years of rework. The Ukrainian construction market in 2025 has both genuinely experienced companies and fly-by-night crews and outright fraudsters. This article will help you distinguish a reliable contractor from an unreliable one - using 7 concrete criteria.
Criterion 1: Official registration and licensing
The first thing to check is whether the company has official registration as a legal entity or sole proprietor. Check the company in the Unified State Register by its tax code at data.gov.ua. A construction company should have KVED code 41.20. For CC3 complexity structures (over 300 m²) a license is required, but most private homes fall under CC1–CC2.
Criterion 2: Real portfolio with property addresses
Any company can show attractive photos on Instagram. A reliable company can show addresses of actually built projects and will let you visit and talk to the owners. Ask for addresses of 3–5 projects built in the last 2 years. If they refuse - that's a suspicious sign.
Criterion 3: A transparent and detailed contract
A serious contractor offers a detailed construction contract that clearly specifies: list of works and materials with quantities; cost broken down by stages; completion dates; the procedure for accepting work; warranty terms; dispute resolution. Never sign a contract that boils down to 'we'll build a house for X amount' without itemization.
Criterion 4: Own team vs subcontractors
Ask directly: who will do the work - a permanent in-house team or hired subcontractors? Both options can be acceptable. A good general contractor may have its own staff for key work and bring in subcontractors for specialized work - this is normal practice.
Criterion 5: Reviews from real clients
Don't limit yourself to reviews on the company's website. Search for the company name in Facebook construction groups and review sites. Ask former clients: were timelines met, were there hidden charges, how did the company respond to complaints. This step will take 1–2 days but may save you from a major mistake.
Criterion 6: Detailed estimate without hidden costs
A reliable contractor provides a detailed estimate with specific line items. An estimate for a 120 m² house should have 50–100 lines. Also clarify what is NOT included: often paid separately are construction waste removal, temporary utility connections, site security, and VAT.
Criterion 7: Warranty on completed work
Minimum acceptable: foundation and load-bearing structures - 5 years; roofing and windows - 3 years; engineering systems - 1–2 years; finishing work - 1 year. The warranty must be written into the contract with a clear mechanism. A verbal promise is not a warranty.
Red flags: signs of an unreliable contractor
Be cautious if a contractor: demands more than 30% advance payment; has no official documents and only accepts cash; pressures you to sign quickly; cannot name specific addresses of completed projects; quotes prices significantly below market rate ($450–600/m²); refuses to include warranty obligations in the contract.
Conclusion
Finding a reliable contractor is not a lottery if you approach the process systematically. Check documents, visit real projects, talk to former clients and carefully read the contract. These steps will take 1–2 weeks but will save you from much bigger problems. Leave a request on domriy.com.
