Ongoing updates, bug fixes, security patches and support for your website or app - whether we built it or not.
We keep existing systems running smoothly rather than leaving them to quietly degrade, integrating with what you already have instead of pushing a rebuild you don't need.
Different systems need different maintenance - ongoing maintenance protects the investment you've already made, rather than just fixing things once they break.
Where relevant: content updates, plugin and CMS updates, broken link fixes, uptime monitoring, scheduled backups, security patching and changes to third-party integrations - keeping your website or web app current and dependable rather than quietly falling behind.
Android and iOS compatibility updates, bug fixes, crash investigation, performance tuning, dependency and API changes, and support with app-store release compliance - so your app keeps working as the platforms around it move on.
Software doesn't stay technically still after launch - here's what tends to happen without regular attention.
Ageing frameworks and libraries can introduce compatibility and security issues over time.
Third-party APIs and services change on their own schedule, not yours.
New data and features can gradually slow a system down if left unchecked.
Browser and OS updates can affect behaviour that used to work fine.
Unpatched systems accumulate known, publicly documented risks.
Small unresolved problems can eventually become business disruptions.
A proactive approach catches problems before they affect your users - we'd rather prevent an issue than explain one after the fact.
Reviewing your system before small issues grow.
Resolving issues and keeping things running smoothly.
Applying updates that close known vulnerabilities.
Regular backups so you're never starting from zero.
Small improvements as your needs evolve.
Changes scheduled to minimise disruption where possible.
Agreed response times, not vague promises.
A consistent point of contact, not a new person each time.
Transparent throughout - you always know what's been checked and what's next.
Review your current site or app, architecture, tech stack and any maintenance history available.
Identify urgent problems, outdated dependencies and compatibility risks, prioritised by impact.
Agree scope, update cadence, monitoring and response expectations.
Verify backups and prepare a rollback approach where the environment supports it.
Carry out approved patches, bug fixes, dependency updates and small enhancements.
Check key workflows, functionality, integrations and responsive behaviour.
Release approved changes through the appropriate deployment workflow for your system.
Track outcomes, flag recurring issues, and share clear updates on what's next.
The principles behind the process above.
Understand system health and current issues.
Rank work by business and technical impact.
Implement the agreed fixes and updates.
Test changes before and after deployment.
Use findings to plan future maintenance.
Depending on your system, support can include some or all of the following.
Maintenance requirements vary by industry, platform and how critical the system is to day-to-day operations.
Three related but distinct parts of keeping a system dependable.
Keeping supported dependencies and software versions up to date to close known, publicly documented vulnerabilities. We don't claim formal security certifications unless we've genuinely been assessed against them.
Scheduled backups with a frequency and retention approach appropriate to your system - agreed as part of the maintenance plan rather than assumed by default.
A backup is only useful if the restoration process is understood in advance. Recovery procedures are set up appropriate to your specific system and hosting environment - we don't promise data can never be lost.
Zerothcode regularly takes on maintenance for websites and apps built by previous agencies, freelancers or in-house teams. We start with an honest review of what's there rather than assuming anything about how it was built.
Where it's part of your maintenance plan, we can monitor areas such as uptime, errors, performance, application logs and integration health. The level of monitoring depends on your system type, hosting and traffic - we'll agree what's appropriate rather than applying a blanket setup.
Tell us what's running, what's going wrong and what you need maintained. We'll review the current system before recommending the right support approach.
Discuss Your Existing SystemDepending on your system, this can cover content and CMS/plugin updates, bug fixes, security patches, performance tuning, backups, uptime monitoring, OS and app-store compliance updates, and general technical support.
Yes - we regularly take on maintenance for systems built by other agencies or in-house teams. We start with a review of the existing code, platform and known issues before agreeing a plan.
Response times are agreed as part of your maintenance plan based on the severity of the issue and your system's complexity - we'll confirm a clear commitment once we understand what we're supporting.
This depends on the system - a content-heavy website may need frequent CMS and plugin updates, while a stable internal app may only need periodic reviews. We agree a cadence based on your platform and traffic rather than a one-size-fits-all schedule.
Yes - security patching and scheduled backups are core parts of our maintenance approach, alongside monitoring for issues before they affect your users.
Small enhancements to existing functionality can often fit within a maintenance arrangement. A larger new module or feature set is usually better scoped as its own project - see Custom Software Development - so we can plan and cost it properly rather than squeezing it into ongoing maintenance.
Maintenance is typically an ongoing arrangement - a website or app needs continued attention as platforms, dependencies and security requirements change over time. We also handle one-off fixes where that's genuinely all that's needed.
Cost depends on the scope and complexity of your system, how frequently updates are needed, and your required response times. Contact us with details of what you need supported and we will provide a clear, no-obligation quote.
Typically, platform and hosting details, access to the relevant code or repository, a summary of known issues, and details of any current providers or third-party integrations. We'll confirm exactly what's needed once we understand your system - we won't ask for sensitive credentials through this page.
Left unattended, a website or app doesn't stay still - dependencies go out of date, security patches go unapplied, and integrations quietly break as the services around them change. Proactive maintenance catches these issues early, rather than leaving you to discover them when something stops working for a customer.
Website maintenance tends to be more frequent and content-driven - CMS and plugin updates, content changes, broken links and uptime checks. App maintenance is shaped more by platform cycles - OS compatibility, app-store compliance updates and crash monitoring - alongside the same underlying need for bug fixes and performance tuning.
Maintenance work generally falls into a few categories: corrective maintenance fixes existing bugs; adaptive maintenance adjusts a system to platform, API or environment changes; preventive maintenance reduces future issues through patches, audits and cleanup; and perfective maintenance improves performance or usability after launch, without changing what the system fundamentally does.
Good practice generally means applying security patches promptly, keeping regular and tested backups, and reviewing access and dependencies periodically. We follow these principles as standard practice - we don't claim formal compliance certifications (such as specific regulatory or accessibility standards) unless that's something we've genuinely been assessed against.
There's no single universal schedule - it depends on how complex your system is, how much traffic it gets, and how often the platforms it depends on change. A high-traffic e-commerce site typically needs more frequent attention than a low-traffic informational website; we agree a cadence based on your actual system rather than a default.
Common warning signs include slower load times than usual, outdated plugins or dependencies, a declining uptime record, an increase in user-reported bugs or complaints, a recent security warning, or simply not knowing when the system was last properly checked over.
Nothing usually breaks all at once. Instead, small issues accumulate quietly - a dependency falls a few versions behind, a third-party integration changes without anyone noticing, a security patch goes unapplied - until enough of them combine into a visible problem or an unplanned outage. Regular maintenance is what keeps that technical debt from building up unseen.
Maintenance covers keeping an existing system working, current and secure - fixes, updates and small enhancements. When a request grows into a genuinely new module, workflow or platform capability, it usually makes more sense to scope it as its own project through Software Development or Custom Software Development, so it gets properly planned and costed rather than squeezed into an ongoing maintenance arrangement.
