How we issue invoices

CleanWhale operates as an intermediary platform (marketplace) that connects you with independent Contractors providing cleaning and other services.

CleanWhale issues you a VAT invoice only for the Order Handling Fee — our remuneration for intermediary services: selecting and verifying the Contractor, coordination, and handling documents and payments.

The service is provided and documented directly by the Contractor, who issues you a separate document for its full value: a VAT invoice if the Contractor is an active VAT payer (VAT deductible on your side), or an invoice without VAT or a bill if the Contractor is exempt (a tax-deductible cost, without VAT deduction).

You therefore receive two documents per order, and both are tax-deductible costs. Your final price and payment method stay the same.

How we calculate VAT

CleanWhale charges VAT only on its own remuneration, not on the value of the service — the seller of the service is the Contractor, not CleanWhale. Our invoice: the Order Handling Fee plus 23% VAT, fully deductible on your side. The Contractor's invoice: VAT depends solely on their status. There is no double taxation — VAT appears at most once on each side.

Revitalise Your Wooden Windows in Koszalin

Historic and classic timber window frames bring an undeniable aesthetic warmth and durability to any home, but exposure to coastal Baltic weather often leads to peeling coats, greyed wood, and failing seals. Replacing them entirely is both expensive and disruptive. CleanWhale offers comprehensive wooden window restoration in Koszalin, preserving your original architecture while renewing timber surfaces, improving energy efficiency, and restoring structural integrity.

Our Window Renovation Process

Our skilled craftsmen carefully strip weathered paint layers, sand and repair structural imperfections, fill deep cracks, apply anti-fungal wood treatments, and seal the surface with durable primers and finish coatings. We also replace deteriorated glazing putty and acoustic seals, while tuning fittings across homes in Koszalin, Mścice, and Mielno so every window operates effortlessly.

Transparent Pricing for Every Project

We believe in straightforward service without hidden fees. The final price is calculated in advance based on the size, quantity, and current state of your timber frames. You see the transparent estimate before placing your order and complete payment securely online.

Easy Online Booking in Koszalin

Select your window dimensions, pick an arrival date that fits your schedule, and book the service in under a minute. Schedule your wooden window renovation in Koszalin today to enjoy beautifully restored joinery that looks stunning and shields your home for years to come.
