Start with your scope and desired outcomes
Before you request quotes, write down what you actually want to build, improve, or renovate. Include measurements where possible, the type of finish you prefer, and any constraints like access to the site or parking for construction company dublin trades. A well-defined scope helps a construction contractor price your project accurately and prevents major changes later. It also makes it easier to compare bids from different contractors side by side.
If you’re considering an addition, think beyond the footprint and focus on how the new space will connect to the existing structure. Ask how they will handle structural support, wall ties, insulation continuity, and weatherproofing at junction points. For example, a two-storey extension requires careful planning around loads, stairs, roof transitions, and internal layout. When the contractor can explain these items clearly, it’s a strong sign they’ve done similar work before.
Verify credentials, process, and the quality checks
A reliable construction company should be willing to share key details about their process, not just their pricing. Look for clear project steps such as site preparation, foundation and structural work, rough-in stages, insulation and airtightness checks, and final two storey extension dublin finishes. Ask how they manage subcontractors, how they schedule inspections, and what documentation they keep for each stage. The best contractors can explain how they track workmanship quality from start to finish.
Licensing, insurance, and references matter, especially for multi-trade builds. Request examples of comparable projects and follow up with past clients when possible. You should also ask about materials selection and why specific products are chosen for your site conditions. If they discuss moisture management, ventilation strategy, and durable exterior finishes, you’re more likely to get a result that performs well over time.
Evaluate quotes for clarity, cost drivers, and flexibility
When you receive a quote, check whether it breaks down labor, materials, and key elements such as foundations, structural steel or blockwork, roofing, windows, and external rendering. A detailed estimate makes it easier to identify what’s included and what could change as the project progresses. Be cautious of bids that are unusually low without a clear explanation, because they may omit items that later become change orders. If the contractor offers transparent allowances for selections, confirm that you can review choices before work proceeds.
Cost drivers often include design complexity, site conditions, and how long the project will take. Ask how they handle unforeseen issues like drainage problems, uneven ground, or hidden defects discovered during demolition. A strong buyer-intent contractor will provide a plan for managing variations and will communicate how costs and schedules may be adjusted. If you’re targeting a two-storey extension, ensure the estimate reflects structural requirements, roofworks, and interior finishing so the final cost aligns with your expectations.

Focus on scope definition, proof of capability, and a quote that explains what you’re paying for and how changes are handled.
