Clearing blocked drains across Dublin since 1968 — day or night.
Most commercial properties only call a drainage company after something has already gone wrong. Our maintenance plan keeps you ahead of that. We inspect, clean and report on your drains on a schedule built around your site.

Every problem on this list is one we see on commercial sites that only call when something breaks. Each is cheaper to prevent than to fix, and a maintenance plan keeps them off your site. Here is what you avoid.
An emergency call-out is charged at a far higher rate than a planned visit. We clean the system on a set schedule, so it is cleared before it fails and forces one.
Grease is the usual culprit, and it builds fastest where you cook. Our plan includes grease trap servicing and kitchen line jetting matched to how hard the kitchen works.
Communal drains serve every unit, so one blockage becomes everyone's problem fast. We run scheduled CCTV checks on shared runs and clear build-up before it reaches a single tenant.
A full interceptor discharges oil into the sewer, and that means fines. We empty it on schedule with our tanker services, so it never reaches capacity.
Left alone, a hairline crack lets in roots and water until the pipe fails. Scheduled CCTV finds it early, while a pipe patch or reline still fixes it without excavation.
Insurers, auditors and the EPA can all ask for proof. You get a written condition report with footage and a defect log after every visit, so the records are always on file.
Planned and preventative maintenance means three things on every visit: we inspect the system, clean it, and report on what we found.
Every visit starts with a camera survey of each accessible run, showing build-up, damage and anything that changed since last time.
Once we can see the system, we jet every run clear, empty the gullies, and service grease traps or interceptors where fitted.
After every visit you get a written report covering what we found, what we cleaned, and what needs attention, ready to file for compliance.

We had an extremely positive experience with Davis Drain Services. Within minutes of calling them out of hours, they arrived to our house to clear a blocked septic tank. It was pumped out promptly before returning the following morning to rectify the issue. At all times they made us feel at ease and explained everything to us clearly. While on site they also provided helpful advice on how to rectify heating issues we were having. We would have no hesitation recommending them for both drainage and plumbing works. Thanks to Alec and team.Posted on Google![]()

Just had Alec out to look at an issue with my boiler. We were without heat and he arrived so quickly after being contacted. He was able to pinpoint the issue straight away and had it fixed in minutes. I also asked advice on an issue with my drains that I have been encountering for a few years and he was able to give me advice on how fix it. Thank you Alec, I am very grateful for all you help.Posted on Google![]()

Great service, fast call out lovely team
The right frequency depends on your property type, how hard the drainage works, and what runs through it. The table below is where we usually start, before a survey sets the exact schedule for your site.
| Property Type | Frequency | What We Focus On |
|---|---|---|
| Restaurants and Hotels | Monthly or quarterly | Grease traps, kitchen waste lines, floor drains and yard gullies. Heavy grease loads need the most frequent cleaning. |
| Apartment Blocks | Every 6 months | Shared soil stacks, communal runs, gullies and rainwater pipes. Regular clearing keeps communal backups off tenants. |
| Offices and Retail | Every 6 to 12 months | WC drainage, staff kitchen waste, downpipes and car park gullies. Lighter use means longer gaps between visits. |
| Petrol Stations and Forecourts | Every 6 months | Oil interceptors, forecourt gullies and storm drains. A compliance-led schedule under SI 630/2019. |
| Schools and Public Buildings | Every 6 to 12 months | High-traffic WCs, kitchen drainage and playground gullies. Visits scheduled around term breaks to avoid disruption. |
These are starting points. We confirm the right frequency for your premises after a free site survey.
We quote only after a free survey. The price depends on your premises, the drains you have and how often the system needs attention.
We come to your site, survey the drainage system, and send back a maintenance plan and a fixed quote. No cost, no obligation.
A restaurant with daily grease output needs far more than an office with light WC drainage. Your premises sets the baseline.
Multi-site operators get one contract covering every location, one schedule and one point of contact.
CCTV inspection only, jetting only, or the full inspect-clean-report package every time. You choose the scope.
Night visits, weekend work or restricted-access sites take more to schedule, and that affects the price.
What commercial operators usually ask before putting a maintenance plan in place.
Planned preventative maintenance (PPM) for drains is a scheduled programme of inspection, cleaning and reporting on a commercial drainage system at agreed intervals. Instead of waiting for a blockage and paying an emergency rate, PPM drainage catches problems early and keeps the system running. You get a predictable cost and a clear record of the drainage condition.
It depends on the property and how hard the drainage is used. Restaurants and hotels with heavy grease output usually need monthly or quarterly visits, while apartment blocks, offices and retail sites are typically every six to twelve months. We recommend a specific schedule after surveying your site.
Every visit covers the same three things: a CCTV inspection of the accessible drains, high-pressure jetting to clear build-up, and a written condition report. Grease trap servicing and interceptor cleaning are included where your site has them. You get the full inspect-clean-report package on every visit.
Yes. Restaurants, shops and busy offices often need drainage work done overnight, early morning or at weekends, and we schedule visits around your opening hours. That keeps the maintenance from interrupting trade or getting in the way of your customers.
Yes, after every visit. The condition report sets out what we found, what we cleaned and what needs attention, with CCTV footage, photos and a defect log graded by priority. You can file it for insurers, auditors or the EPA and share it with your management team.
We cover Dublin, Meath and Louth. Based in Skerries, we work across north County Dublin and Fingal, and out to Drogheda, Dundalk, Navan and the surrounding towns. If your site is in that area, we can put it on a maintenance schedule.
Yes. If you manage several premises across Dublin, Meath or Louth, a single drainage maintenance contract can cover all of them, with one schedule, one point of contact and one monthly invoice. We inspect and report on each site individually, so you can see the condition of every location.
Any issue we find is flagged in your condition report with a priority rating. If it is minor we can often deal with it on the same visit; if it needs a separate repair, we quote for the work before doing it. Either way, you know about it before it becomes an emergency.
Tell us the premises type and we will survey the site, recommend a schedule, and come back with a price.
