How to Choose a Renovation Company in Altea: Guide

Choosing a renovation company isn’t just about comparing who charges less. It’s the decision that determines whether the work finishes on time and within budget, or turns into months of delays, cost overruns and unanswered calls. In Altea, where long-time locals live alongside foreign owners who only spend a few weeks a year in their second home, choosing wrong is even more costly: there isn’t always time to stay on top of the site to fix things as they go.

This guide covers what to check before signing with a renovation company, with the specific documents required by Altea Town Hall and the signs that separate a serious company from one that promises a lot and delivers little.

What to check	How to verify it	Why it matters
Legal registration and accreditation	Tax ID, registration with the Registry of Accredited Companies	Avoids hiring an unlicensed operator with no legal cover
Public liability insurance	Ask for the current certificate, not just their word	Covers damage to the home or third parties during the work
Itemized quote	By line item, not a single figure	Allows comparison between companies and spots what’s missing
Verifiable references	Past work in Altea or Marina Baixa, with an address or photos	Confirms real experience in the area, not just a catalogue
Timeline in writing	Estimated schedule by phase, not just a delivery date	Catches delays early instead of discovering them late
Payment schedule	Payments tied to work milestones, not everything upfront	Protects against the job being abandoned midway

Define the project and compare at least three quotes

Before contacting any company, it’s worth being clear about what needs renovating: just finishes, a kitchen and bathroom, or a full renovation that touches the layout and installations. The more specific the brief, the more comparable the quote each company gives, because not everyone prices the same way if the starting point isn’t well defined.

Asking only one company for a quote — even if it comes recommended — leaves no reference point for whether the price is reasonable. The usual approach is to contact at least three renovation companies in Altea or nearby and have them visit the home before giving a figure, rather than quoting from photos or a phone description alone. A company that gives a fixed price without having set foot in the home tends to adjust that price upward once the work begins.

It’s worth being wary of both the most expensive and the cheapest quote if they don’t come with a clear explanation of what they include. The difference between two quotes is almost always in the materials chosen, whether they include waste management and permits, or whether the price allows for reasonable contingencies. Comparing only the final number, without looking at the breakdown, is the most common mistake at this stage.

If the project includes a full renovation with layout or structural changes, this is a good time to also review what phases the full process requires and what budget margin to leave for the unexpected.

Check that the company is registered and insured

In Spain, any renovation company must have a tax ID and be registered for economic activity. But that’s the legal minimum, not a guarantee of quality. What makes the real difference is checking whether it’s listed in the Registry of Accredited Companies (REA), mandatory for companies working in construction, which certifies that they meet occupational risk prevention requirements.

Document or insurance	What it’s for
Tax ID and business registration	Confirms the company legally exists, not just an unstructured crew
Registry of Accredited Companies (REA)	Certifies compliance with occupational risk prevention requirements
Public liability insurance	Covers damage to the home, neighbors or third parties during the work
Building permit or responsible declaration	Municipal permit from Altea Town Hall, depending on the type of renovation

Public liability insurance is the point most often overlooked. It’s not enough for the company to say they have it: it’s worth asking for the current certificate with the policy number, because an expired policy covers nothing if something goes wrong — a leak affecting the flat below, an accident during demolition. A serious company has no problem showing it; one that makes excuses not to is a clear warning sign.

The building permit or responsible declaration needed depends on the type of renovation: changing only finishes usually only requires a responsible declaration, while touching the layout or structure requires a building permit from Altea Town Hall. An experienced local company knows how to tell which one applies to each project and handles the paperwork; if they don’t bring it up on their own, it’s worth asking directly before signing.

Ask for examples of past work and references in the area

Looking at photos from a generic catalogue doesn’t say much about how a company works specifically in Altea. It’s more useful to ask for examples of renovations completed in the area — Altea’s old town, Altea la Vella, nearby residential areas — with an approximate address or at least enough detail to verify they’re real, not reused stock images.

Talking to past clients, even just by phone, reveals things no photo shows: whether the company met the deadlines it promised, whether the final quote matched the initial one or spiked with poorly justified “unforeseen extras,” and how it resolved the problems that came up during the work — because something always does.

In Altea, a significant share of owners who renovate are foreign — Belgian, Dutch, English, German — with a second home they only visit a few weeks a year. For this type of client, remote communication (reports with photos, follow-up video calls, the ability to manage the job without the owner present) matters as much as the quality of the work itself. It’s worth asking explicitly whether the company has experience managing renovations for owners who aren’t in Spain during the work, because not every local company is set up for that.

What a detailed quote should include

A one-page quote with a total figure and little else is the main source of surprises midway through a job. A proper quote breaks down each line item and explicitly states what’s excluded, so nothing shows up as an “extra” halfway through the renovation.

Line item	What it should specify
Demolition and waste management	Estimated volume and whether the skip or waste handler is included in the price
Installations (electrical, plumbing)	Whether it’s a full replacement or just repairs to damaged parts
Finishing materials	Brand or reference range, not just a generic “flooring” or “tile”
Labor by trade	Broken down, not lumped into a single block that’s hard to audit
Permits and municipal fees	Whether they’re included in the quote or charged to the owner separately
Contingency margin	An explicit percentage, usually 10-15% of the total

When a quote doesn’t specify the range of materials, it’s common for the company to price using the cheapest option and then offer “upgrades” at extra cost once the work has started. Asking for the specific material reference — not just the category — avoids that surprise.

It’s also worth asking explicitly what happens if something unforeseen comes up beyond the agreed margin: how it’s communicated, how the extra cost is approved before it’s carried out, and whether anything needs to be signed in writing. A company with no clear procedure for this tends to sort it out on the fly, and “on the fly” almost always means more expensive than expected.

Communication, timelines and warning signs before signing

How a company responds before the contract is signed tends to predict how it will behave during the work. If it’s hard to get a home visit, if answers to specific questions are vague, or if the quote takes weeks to arrive without explanation, these are signs that communication during the job won’t be smooth either.

Before signing, it’s worth asking for a schedule broken down by phase, not just a final delivery date. A phase-by-phase schedule makes it possible to catch delays early — for example, if the installations phase runs longer than expected — instead of finding out once the promised delivery date is almost due.

Another warning sign is insistence on being paid the full quote upfront. What’s normal and reasonable is a payment schedule tied to work milestones (start, end of demolition, end of installations, finishes, final delivery), not a single upfront payment that leaves the owner with no leverage if something goes wrong midway.

A low price isn’t always a good price

When a quote comes in far below the rest, it’s almost never because that company works cheaper in a sustainable way: it usually means line items are missing (permits, waste management, insurance), that the planned materials are a lower grade than what was quoted in the other offers, or that the contingency margin is zero and will show up as an added cost as soon as the work starts.

A very low price can also reflect that the company isn’t properly registered or doesn’t carry public liability insurance, which lowers its fixed costs but shifts all the risk onto the owner if something goes wrong. An initial saving of a few hundred euros can turn into thousands if damage has to be repaired that insurance would have covered, or if the work stops for lack of the required permit.

This doesn’t mean always choosing the most expensive quote. It means comparing quotes that are similar in coverage and detail, and being wary of any offer that stands out only for being much cheaper without a clear explanation of why.

Most common mistakes when choosing a renovation company

Hiring the first company that responds, without comparing at least two or three quotes with the same level of detail.

Trusting a verbal or phone quote without a prior home visit, which almost always ends in an upward adjustment once the company sees the real state of the property.

Not asking for the public liability insurance certificate, assuming “every company has it” without checking.

Paying the full quote upfront, without tying payments to specific work milestones.

Not asking what happens with unforeseen costs: how they’re communicated, how they’re approved, and whether the agreed margin is stated in writing in the quote.

For owners who don’t live in Altea year-round, not checking in advance whether the company has experience managing renovations remotely, with photo or video call follow-ups.
