Flexible Upgrades, Targeted Comfort & Hands-On Collaboration

Not every property requires a full-house overhaul. Whether you want to upgrade a single freezing room, modernize your insulation step-by-step, or actively participate in building your dream chalet, our partial renovation services give you maximum flexibility.

From targeted thermal fixes to professional DIY guidance, we help you optimize your home or Akiya at your own pace and budget.

1. Targeted Thermal & General Upgrades

If a full retrofit isn't in your immediate plans, partial renovations can still deliver a dramatic improvement in daily comfort:

• Single-Room Thermal Retrofits: Upgrade high-use spaces—like the main living area, home office, or master bedroom—with high-density insulation and double/triple-glazed windows.

• Window & Door Replacements: Swap cold, drafty single-pane aluminum frames for high-performance wooden or PVC thermal windows (ECO+ BLIND integration available).

• Bathroom & Damp-Area Upgrades: Eliminate winter "heat shock" and subfloor rot by insulating cold bathrooms, changing rooms, and entryways.

• Roof & Ceiling Insulation: Stop warm air from escaping through the roof in winter and block intense summer heat from entering.

2. DIY Collaboration & Self-Build Support 

In Europe and North America, doing hands-on work on your own property is a proud tradition. In Japan, traditional contractors rarely allow client involvement. At Ecoplus, we welcome it.

If you want to reduce costs or personally invest your labor into your house or chalet, we offer a unique hybrid partnership:

How We Work Together

• We Handle the Heavy & Technical Lifting: Our Swiss-trained master carpenter and team take care of critical structural work, framing, airtight sealing, vapor barriers, and specialized insulation blowing.

• You Do the Finishing Touches: You take over manageable tasks like painting walls, installing floorboards, applying natural plaster (clay/lime), or assembling interior finishes.

• Cost Reduction: By contributing your own labor, you directly lower your overall construction budget without sacrificing structural quality or thermal performance.

3. Professional On-Site Consulting & Partial Contracting

Already have a local team, or planning to do most of the renovation yourself? We also offer consulting and specialized trade services:

• Pre-Purchase & Thermal Assessments: We inspect old properties and Akiya before you buy, advising you on thermal feasibility, structural soundess, and estimated costs.

• Insulation & Airtightness Consulting: We design the insulation strategy and moisture management system for your project, ensuring you avoid common mistakes like trapped dampness and mold.

• Partial Contracting: Hire us strictly for specialized tasks—such as designing the thermal envelope, installing Pavatex wood-fiber boards, or building custom timber features—while you manage the rest.
