Installation and renovation in villas and apartments across the Algarve.
We work in occupied homes, with our own team and 25+ years on site in the region.
Yes. iStarTec installs solar thermal and underfloor heating and replumbs private houses across the Algarve, including in occupied homes. This is renovation and system replacement work — the company does not do one-off repairs, call-outs, maintenance contracts or drain clearing.
Three kinds of job, all held to the same technical standard as the professional work we do for construction companies. Each service is a complete installation, designed to last decades.
Solar energy
Put the Algarve's 1900 kWh/m² of sunshine to work heating your hot water. Bosch system, payback of 5 to 8 years. Installed in 2-3 days.

Thermal comfort
Silent comfort, an even temperature through the room, minimal running cost with a heat pump. Uponor PEX pipe (10-year warranty). Possible in almost any house.

Renovating the house
Replace old galvanised iron or perished PVC. Modern multilayer or PEX on accessible manifolds. The end of leaks, noise and low pressure.
See service →A clear process, with no surprises. The site visit and quote are free — you only decide to go ahead once you know exactly what you will pay and how long it takes.
A call or email to tell us what you have in mind. We come to your house, measure up and assess what is feasible. Free and with no obligation.
Within 5 working days you get a written quote with materials, labour, timescale and validity. No hidden costs.
A team of 2 to 4 technicians, at the agreed hours. In an occupied home we always leave water and power available and clean up at the end of each day.
1 year of iStarTec warranty on workmanship and 2 years on materials. Equipment carries additional manufacturer warranties (Bosch, Uponor). Documentation handed over in writing.
We do not do small repairs (a dripping tap, a broken cistern, blocked drains). For those, we recommend a local repair plumber — it will cost you less than sending our team out.
We do not do domestic service contracts or 24-hour call-outs. We concentrate on full renovations, where our technical experience makes a real difference.
We do not do natural gas installations or gas certifications. We recommend specialists for that part.

Contratei a IStarTec para a instalação de painéis solares na minha moradia em Faro e fiquei extremamente satisfeito com todo o processo. Desde o primeiro contacto, a equipa demonstrou profissionalismo, conhecimento técnico e total transparência. A instalação foi concluída dentro do prazo e com um acabamento impecável. Recomendo a IStarTec a quem procura energia solar, eficiência energética e um serviço de confiança em Faro e no Algarve.
Excelente empresa. Desde o primeiro contacto até à conclusão da obra, tudo correu de forma muito organizada. Pessoas competentes e de confiança, difícil de encontrar hoje em dia.
A great experience overall. The service was very professional, and the team was highly qualified and efficient. Everything ran smoothly, highly recommend!
Both. Our 25+ year track record is in residential construction for developers, but we now also take on work for homeowners — provided it is a full renovation or a system replacement (solar, underfloor heating, the whole house replumbed). We do not do small repairs or one-off call-outs.
Yes. Most private clients want the system replaced without moving out. We phase the work to keep disruption down: we arrive early, protect the space, leave water and power available at the end of every day, and clean the work area before we go.
It depends on the service: solar thermal typically 2 to 3 days; underfloor heating in a villa between 1 and 2 weeks (with floor works); a full plumbing renovation 2 to 4 weeks. We always give you a detailed schedule before starting.
iStarTec warranty: 1 year on installation workmanship and 2 years on materials. Manufacturers add their own — Bosch up to 10 years on some collectors, Uponor 10 years on PEX pipe. You always get copies of the warranties in writing when the job is finished.
No. We focus on full renovations and system installations — we do not do domestic service contracts or 24-hour call-outs. For a single leak or breakdown, we recommend a local repair plumber.
Yes. A solar thermal installation for domestic hot water can qualify for the PRR / Environmental Fund energy efficiency programme and for the Portuguese income tax deduction on renewable energy equipment. We supply all the documentation you need to apply.
